RV Detailing and Reconditioning in Yorba Linda

Because oxidation is a physically degraded layer, not a film of dirt. Ultraviolet light breaks down the resin at the surface, leaving a chalky, porous layer that scatters light. That is what makes an oxidized coach look flat and faded even when it is clean.

Wax fills that porous layer temporarily. Oil in the wax darkens the chalk, gloss appears to return, and within weeks the oil evaporates and the chalk is back. Owners conclude the wax was poor quality. It was doing exactly what wax does on a surface that needed something else.

Compounding removes the degraded layer mechanically with an abrasive and a machine, exposing sound gelcoat underneath. That is followed by polishing to refine the finish and then a sealant or coating to protect it. Southern California sun makes this a recurring requirement rather than a one time fix, which is worth knowing before the work is bought.

Three things: area, condition and height. A 40 foot coach has roughly six to eight times the exterior surface of a car. Condition determines how many machine passes each area needs, and heavily oxidized gelcoat can need a compounding pass, a refining pass and a finishing pass where a maintained surface needs one.

Height is the underestimated factor. Everything above about six feet needs scaffolding or a lift, which means setting up, working a section, moving, and setting up again. That is unavoidable and it is real time.

Detail work is posted at $95 per hour and quoted against assessed hours. We look at the vehicle, judge the condition honestly and give a range. What we do not do is sell a flat package that quietly assumes a small unit in good condition and then discovers otherwise.

• Exterior surface area, which on a large coach is many times that of a car
• Oxidation severity, which determines the number of machine passes
• Working height, since anything above six feet requires scaffolding
• Graphics condition, as failing decals may need removal rather than polishing
• Interior condition, particularly upholstery, headliner and cabinetry

Detailing works with the existing surface. Refinishing replaces it. The dividing line is whether there is enough sound material left to correct.

On gelcoat that is a judgement about thickness. Gelcoat is applied at a few thousandths of an inch and compounding removes some of it every time. A coach that has been compounded three times may not have enough left to survive a fourth, and cutting through gelcoat to the laminate is not recoverable by polishing. At that point refinishing with a modern clear coat system is the honest recommendation.

On painted surfaces the same logic applies to clear coat thickness, which can be measured. Clear coat that has already begun to fail, showing cloudiness or peeling edges, cannot be polished back. Attempting it removes what is left and accelerates the failure, which is why we measure and assess before quoting correction work rather than after.
