Where 250 Hours Go on a Full Coach Repaint
A full paint job strips the vehicle back to a uniform substrate, corrects every surface defect, then refinishes the whole shell in one scheme. It runs $5,000 to $35,000 across 40 to 250 hours. Roughly three quarters of those hours happen before any colour is sprayed.
Ballpark range $5,000 to $35,000 at 40 to 250 hours of labor. See the posted rate card.
Why is preparation most of the job?
Because paint is a thin film that copies what is underneath it. A sanding scratch that is too coarse shows through. A patch of failing old finish under new colour lifts. A seam that was not sealed leaves a line. None of that can be corrected after spraying, so all of it is corrected before.
On a coach the surface area is enormous, and the prep is proportional. Every square foot gets sanded to a consistent key. Every piece of failing finish is removed back to something sound. Every ding, crack and delaminated patch is repaired. Every seam and penetration is inspected and resealed, because a leak under fresh paint is the most expensive kind.
Then comes masking, which owners consistently underestimate. Glass, lights, trim, rub rails, awning rails, vents, antennas, tanks and hardware either come off or get masked, and coming off is usually better because a masked edge shows. On a 40 foot coach that is a day or more of work on its own, and it happens again in reverse at the end.
Priming and blocking follow. High build primer goes on, then it is blocked flat with long boards, then guide coat reveals what the blocking missed, then it is blocked again. That cycle is where a surface either becomes straight or does not.
What finish system suits which vehicle?
- Single stage
- Colour and binder in one product. Fewer hours, lower material cost, and it polishes well. Common on commercial units, trailers and fleet vehicles where durability and cost matter more than depth of finish.
- Base coat and clear coat
- Colour first, then clear over it. The clear carries the ultraviolet inhibitors and the gloss, so the system holds up far better in Southern California sun. This is the default on coaches and on anything with metallic content.
- Multi stage
- A ground coat, a translucent mid coat and clear. This is how pearls and candies work, and it is the most demanding to apply and to repair later, because the mid coat's appearance depends on how much of it went down.
Paint supplies calculate at $55 per paint hour on every estimate, which is why the finish system choice moves both the hours and the materials at once. A full body pearl scheme on a 40 foot coach lands near the top of the $5,000 to $35,000 band; a single stage refinish on a box truck lands near the bottom.
What does the booth actually do?
It controls three things: airborne contamination, temperature and airflow. Contamination is why a coach sprayed outside will have dust and insects in the finish no matter how careful the painter is. Temperature is why cure is predictable indoors and a gamble outdoors. Airflow removes solvent vapour so the film flows and levels rather than trapping solvent under a skinned surface.
The constraint that matters for RV work is size. Most collision booths are built for cars and will not accept a 40 foot coach, which is why full coach refinish is not a service most body shops can offer regardless of skill. The booth here is sized for a 45 foot vehicle, which is the reason full refinish work sits on the menu at all.
Colour is sprayed out on a test card before the vehicle sees any of it, and checked under booth light and under daylight, because metallics in particular read differently under different sources. That card also becomes the reference if a panel needs attention later.
What should you decide before booking?
Four decisions save time and money if made early.
- Same colour or a change? A colour change means door jambs, compartment interiors and edges have to be addressed or the change shows every time something opens. That is real additional hours.
- What happens to the graphics? Recreated in paint, cut in vinyl, simplified or dropped. Each is a different cost, and it is decided before masking, not after.
- What repairs go in first? Delamination, cracks, seam failures and soft spots all get repaired before paint. Painting over them wastes the paint.
- How long can the vehicle be here? A full refinish occupies a bay for weeks. Scheduling it around a season you do not use the coach is usually the right move.
Related work includes custom colour matching if you are matching an existing scheme, custom paint and graphics for the scheme itself and paint correction and polishing for the finishing stage. Bands are on the price sheet.
Questions we get asked
Can you paint over gelcoat?
Yes, and it is routine on coaches. The gelcoat is sanded to a uniform key, any oxidized or chalking surface is removed rather than sealed over, and an appropriate primer goes down. Chalk left under primer is the classic cause of a refinish that peels in sheets a year later.
How long will a full repaint last?
A properly prepared base and clear refinish on a coach that is washed and kept out of continuous sun holds its gloss for many years, well beyond what gelcoat manages. Storage is the biggest variable, and a covered coach will always outlast an uncovered one.
Can you match my existing colour if only part is being painted?
That is a blend job rather than a full paint job and it is handled under spot repair and blend matching. A full refinish removes the matching problem entirely because everything is sprayed from the same mix.
Do you paint commercial trucks and fleet vehicles?
Yes. Fleet refinish work runs through the same booth, usually in single stage for durability and cost, with graphics and compliance markings reapplied afterward. Scheduling around a fleet's downtime window is part of the conversation.
