# RV Dent Removal on Aluminum, Fiberglass, and Painted Steel

> Most dent work at our Westminster shop lands between $500 and $3,500, with a shallow ding in one aluminum sheet at the low end and a creased sheet that has to be cut out and replaced at the top. Aluminum siding stretches when it dents and does not spring back the way automotive steel does, so paintless technique has a narrow window. The honest deciding factors are metal type, access from behind, and whether the panel is creased or merely pushed in.

RV dent removal is a different trade from automotive dent work, because the panel in front of you is usually 0.024 inch aluminum over a wood or aluminum stud wall, not a stamped steel door skin. Access from behind is blocked by batt insulation, wiring, and framing. Our team in Westminster looks at the metal, the access, and whether the sheet has stretched before quoting anything. That single answer drives the whole repair plan, including paint.

## Why Aluminum Siding Does Not Act Like Car Steel

Steel has memory. Push a shallow dent out of a steel fender and the metal wants to travel back toward its original shape, which is the entire reason paintless dent repair works so well on passenger cars. The aluminum sheet on a stick-and-tin trailer is roughly 0.024 to 0.032 inch thick and it does not behave that way at all. When it dents, it stretches. Stretched aluminum has nowhere to go when you push it back, so it sits proud, or it oil cans in and out under light thumb pressure.

That is the real limit on paintless technique for a travel trailer. On a very shallow, very round dent in an area that has not stretched, a patient hand with glue tabs and a knockdown can improve the panel to the point where you only see it in raking light at a low angle. On anything with a sharp low point, a crease, or torn metal at a rivet line, pulling drives more stretch into the sheet and makes the finished result worse. We say that up front instead of billing hours into a dead end.

Access is the second hard limit. On a car you can usually reach the back of a panel through a door cavity or a wheel well. On a trailer the back side of that sheet is fiberglass batt insulation, one by two furring or aluminum studs on sixteen inch centers, wiring runs, and often the back of a cabinet. Getting a rod or a hand behind the low point means opening the interior wall, which turns a small cosmetic repair into a teardown with trim, paneling, and reassembly labor attached.

## How We Choose Between Pushing, Filling, and Replacing

The first pass is a straightedge and a light. We lay a rule across the dent to read the depth, then rake a light across the panel at a shallow angle to find the edges of the stretch. A dent that is deeper than about a quarter inch, or one that runs across a rivet line or a seam, is almost never a push-and-finish job. A shallow saucer in the middle of a sheet with no torn fasteners usually is.

When we fill, we fill thin. Body filler over aluminum needs a clean, sanded, etched surface and a thin build, because a thick slug of filler on a flexible sheet that expands and contracts in Southern California heat will eventually crack or telegraph a shadow line. If the low spot needs more than about an eighth of an inch of filler to level, we stop and price the sheet replacement instead, because the filled version will look wrong within a season or two.

Sheet replacement means cutting the damaged siding at the nearest natural break, usually a seam or a molding line, drilling out rivets, and installing new siding of the same profile. It costs more in labor and paint than a push and fill, but it is a permanent repair rather than a cosmetic one. Body and paint labor runs $210 per hour, and paint supplies add $55 per paint hour, so the decision between the two paths is worth having in plain numbers before work starts.

- Dent depth measured against a straightedge, not judged by eye
- Whether the low point crosses a rivet row, seam, or corner molding
- How much of the sheet has stretched, read under raking light
- Whether the interior wall can be opened without gutting cabinetry
- Filler thickness needed to level the repair, capped at about an eighth of an inch
- Whether the siding profile is still made in a matching pattern

## Dents in Fiberglass Are a Laminate Problem

A fiberglass sidewall is not one material. It is a sandwich: a thin filon or gelcoat skin, an adhesive layer, a foam or luan core, and an inner skin. When something hits it hard enough to leave a visible low spot, the skin rarely stretches the way metal does. Instead the impact crushes the core underneath and breaks the adhesive bond between the skin and that core. What looks like a dent is actually a delamination with a dish in the middle of it.

That changes the repair completely. Pushing on it from behind, even if you could reach it, does nothing useful because the crushed foam will not rebuild itself. The correct sequence is to map the loose area by tapping across the panel and listening for the dull, hollow tone that marks the edge of the debond, then inject resin into the void, clamp or vacuum the skin flat while it cures, and refinish the surface. If the core is crushed rather than merely debonded, that core section has to come out and be replaced.

Owners are often surprised that a smaller-looking mark on a fiberglass wall prices higher than a bigger dent in aluminum. The reason is cure time and clamping time, not material cost. A resin injection repair holds the shop bay for a day or more of clamped cure before anyone can touch the finish, and the paint work on a laminated wall almost always means blending into adjacent panels rather than stopping at a seam.

## Painted Steel Truck Bodies and Fleet Panels

Commercial truck bodies, box vans, and service bodies are a different animal, and in a good way. Steel panels have memory, they are usually thicker than RV siding, and there is often real access behind them through a door opening or an equipment compartment. Paintless dent repair genuinely works on many of these, and a dock rash dent on a painted steel side panel can sometimes be pushed out and polished with no refinishing at all.

Where it gets more involved is when the paint has cracked or the metal has creased over a body line. Once the finish is broken, the panel needs at minimum a spot repair with primer, base, and clear, and Southern California sun on a fleet vehicle that lives outside makes color match on faded single stage paint a real conversation. We check the panel with a spectrophotometer reading and a sprayout card before committing to where the blend will end.

For fleets, the calculus is downtime. A truck sitting in our bay is a truck not earning. We schedule fleet dent work in batches where we can, group the panels that need refinishing so they share a paint cycle, and give a written sequence so a dispatcher knows which unit comes back on which day rather than getting a vague estimate.

- Steel panels with intact paint are the best candidates for pushing without refinishing
- Cracked paint over a dent always means primer, base, and clear on that panel
- Faded single stage fleet paint needs a sprayout card before the blend is set
- Body line creases in steel usually need shrinking with heat, not just pushing
- Batch scheduling keeps multiple fleet units out of the shop at the same time

## What Makes a Crease Cost Several Times a Round Ding

A round ding is a single low point with metal that moved in one direction. A crease is a fold, and a fold means the metal along that line has been worked, thinned, and stretched along its entire length. You cannot push a fold out. You have to work the metal back along the whole run, and on thin RV siding you usually cannot, which is why a crease so often ends the conversation at sheet replacement instead of repair.

The labor multiplier is straightforward once you see it that way. A four inch round dent might be an hour of metal work and an hour of finishing. A four foot crease running diagonally across two sheets means drilling out two rows of rivets, pulling corner and seam molding, removing and replacing both sheets, rebedding the molding in fresh butyl, then refinishing an area large enough to blend. At $210 per hour for body and paint labor, that difference shows up fast in the estimate.

There is also a paint dimension. Small dents in the middle of a panel can often be spot repaired and blended within that panel. A crease that crosses a seam forces the refinish area past the natural break, which means the adjacent panel gets pulled into the blend, and sometimes the panel after that. Paint supplies bill at $55 per paint hour, so a larger blend area moves both labor and material at once.

- Round dents move metal in one direction and often finish inside one panel
- Creases thin and stretch metal along a line that cannot be pushed back out
- Crossing a seam pulls neighboring panels into the refinish area
- Rivet removal and rebedding add labor that a simple dent repair never touches
- Larger blend areas raise paint supply billing at $55 per paint hour
- Sheet replacement is often cheaper than chasing a crease with filler

## Getting an Estimate and Planning the Downtime

Bring the unit in or send clear photos taken from three angles with a light raking across the damage. Photos are enough to give a range. They are not enough to write a firm number, because the thing that changes the price most is what we find when trim comes off and we can see whether fasteners are torn or the substrate behind the sheet is wet. Estimates are a paid service, and the estimate charge is credited against an authorized repair.

Once you approve the work, jobs above $2,000 take a 50 percent deposit so we can order siding and materials. Parts carry 100 percent markup at or under $100 and 35 percent above $100, and sales tax of 7.75 percent applies to parts and materials but not to labor. You will see all of that itemized rather than folded into a single number, because a line item estimate is the only way to have a real conversation about scope.

Our facility runs about 35,000 square feet and roughly 75 or more vehicles a month, and we hold BAR license ARD00288521 and EPA registration CAL000367879. Call our office at (949) 799-3387 to get on the schedule. Tell us whether the unit is your daily living space or seasonal storage, because that changes how we sequence the work and whether we can stage it around a trip.

## Frequently asked questions

### Can you do paintless dent repair on my travel trailer?

Sometimes, on a narrow set of dents. Paintless work depends on metal springing back toward its original shape, and thin aluminum siding stretches instead of springing. A shallow, round, saucer-shaped dent in the middle of a sheet, away from rivets and seams, can often be improved to the point where it only shows in raking light. A crease, a sharp low point, torn metal at a fastener, or any dent you cannot reach from behind is not a paintless candidate. We check depth against a straightedge and read the stretch with a light before quoting, so you get a straight answer instead of billed hours on an attempt that was never going to work.

### How much does one dent actually cost to fix?

Dent work at our shop runs from about $500 to $3,500 or more, and the spread is real rather than padding. At the low end you have a single shallow ding in one aluminum sheet, pushed, thin filled, and spot refinished inside that panel. At the high end you have a creased sheet that has to be cut at the seams, the rivets drilled, the siding replaced, corner and seam molding rebedded in fresh butyl, and a blend that carries into adjacent panels. Body and paint labor is $210 per hour and paint supplies bill at $55 per paint hour, so the labor path you take drives nearly the whole number.

### Why is a crease so much more expensive than a round dent?

Because a crease is a fold in the metal, not just a low spot. Along that fold the aluminum has been worked, thinned, and stretched over its entire length, and there is no way to push a fold back to flat on siding that thin. A four inch round dent might be two hours of work. A four foot crease across two sheets means drilling rivet rows, pulling molding, replacing both sheets, rebedding seams, and refinishing an area that reaches past the natural break into the next panel. The cost is not a multiple because a crease is worse to look at. It is a multiple because it is a different repair.

### My fiberglass sidewall has a dent. Is that the same repair?

No, and this trips up a lot of owners. A fiberglass sidewall is a laminate: outer skin, adhesive, foam or luan core, inner skin. An impact does not stretch the skin the way it stretches metal. It crushes the core and breaks the bond between skin and core, so the visible dish is really a delamination. Repair means tapping the panel to map the hollow-sounding edge of the debond, injecting resin into the void, clamping or vacuuming the skin flat during cure, and refinishing. If the core itself is crushed rather than just loose, that section of core is removed and replaced. Cure and clamp time is why these often price above a similar-looking aluminum dent.

### Will the repair area match the rest of my siding?

On a repaired area, yes, that is the standard we work to. We pull a color reading, spray a test card, and confirm the match before anything goes on the vehicle. The complication on older units is fade. A ten year old sidewall that has lived outside in Southern California sun is not the color it left the factory, so matching factory code paint would leave you with a bright patch. That is why we blend into adjacent panels rather than stopping hard at the repair edge, and why a larger blend area sometimes shows up on the estimate for what looks like a small dent.

### Can you fix a dent without repainting anything?

Occasionally, and mostly on painted steel commercial bodies rather than RV siding. If the finish over the dent is completely intact and the metal has enough memory to be pushed and polished, you can walk away with no refinishing. On thin aluminum RV siding this is rare, because the pushing process itself usually disturbs the coating, and the panel typically needs at least a thin skim and a spot refinish to read flat. If a no-paint outcome matters to you, say so at the estimate and we will tell you honestly whether your specific dent is a candidate.

### How long will my RV be in the shop for dent work?

Plan on three days to three weeks. A single push, fill, and spot refinish on one panel can move through in a few days if the bay is open and the paint schedule cooperates. Sheet replacement stretches the timeline because siding has to be sourced in a matching profile, and discontinued patterns take longer to run down. If the repair reaches into a laminated wall, add clamped cure time that nobody can rush. We give you a written sequence at approval and update you if a material lead time changes the finish date.

### Do I have to pay for the estimate?

Yes. Writing a real estimate on an RV means putting the unit on a lift or a level pad, raking light across the panels, sometimes pulling a piece of trim to see whether fasteners are torn or the substrate is wet, and pricing materials and labor line by line. That is a paid service, and the charge is credited against the repair once you authorize the work. If you want a rough range before you drive over, send photos from three angles with a light across the damage and we will tell you which bracket you are likely in. Call our office at (949) 799-3387.
