OCRV Center corrects, decontaminates and coats RVs, vans and trucks in shop for West Covina owners. **Ballpark range.** $1,200 to $9,000. Ranges are planning figures, not a quote. Final numbers come from a written estimate on your vehicle. ## What a ceramic coating does and what it does not A ceramic coating is a liquid polymer that cross links into a hard, thin, transparent layer chemically bonded to the surface it was applied to. Once cured it becomes a sacrificial barrier. Ultraviolet light, acid rain, bug residue, road film and hard water attack the coating instead of attacking your clear or your gelcoat. It is also extremely slick, which is why coated vehicles release dirt so easily and dry with far fewer spots. What it does not do is make the vehicle impervious. A coating does not stop rock chips, it does not prevent scratches from a dirty wash mitt, and it does not repair anything that is already damaged. It also does not last forever. On a vehicle living outdoors in inland Los Angeles County, expect meaningful protection for a few years with proper maintenance, less if the rig is washed with harsh chemicals or brushes. The honest value proposition on a large vehicle is time and consistency. A coated 40 foot coach washes in a fraction of the time an uncoated one does, holds gloss between washes, and does not need waxing on a schedule. On a vehicle with hundreds of square feet of surface, that difference compounds fast. ## Preparation is most of the job A coating is only as good as the surface underneath it, and it locks in whatever is there. Applying one over swirl marks and oxidation seals those defects in for the life of the coating. That is why every coating we do starts with decontamination and correction rather than with the coating itself. Decontamination means a proper wash, then chemical removal of iron particles and tar, then mechanical decontamination with a clay bar or clay media to pull embedded contamination out of the surface. On a rig that has been parked near industrial areas or driven behind trucks for years, this step alone changes how the surface feels. Correction follows: compound and polish to level oxidation, swirls and water etching. Then a panel wipe with a dedicated solvent removes every trace of polishing oil, because coatings will not bond to residue. Only after the wipe does the coating go on, applied panel by panel, leveled by hand while it is still flashing, and inspected under lighting from multiple angles to catch high spots before they cure. - Wash and chemical decontamination for iron and tar - Mechanical decontamination with clay media - Machine correction to level oxidation, swirls and etching - Panel wipe to remove all polishing residue - Coating applied and leveled panel by panel, then inspected under multiple light angles - Controlled cure indoors before the vehicle leaves the property ## Coating gelcoat, paint, glass and fiberglass caps Painted surfaces are the straightforward case. Modern coatings bond well to cured urethane clear and behave predictably. The only caution is timing on a freshly refinished vehicle: clear continues releasing solvent for weeks after spray, and sealing it early traps that solvent and causes dieback. We wait out the cure window, which typically runs 60 to 90 days. Gelcoat is more absorbent and more porous than paint, and it usually needs more correction beforehand. It also tends to consume more product. The payoff is larger though, because gelcoat oxidizes faster than clear does and a coating is the most effective thing available for slowing that down on a travel trailer or fifth wheel living outdoors. Glass benefits enormously. A coated windshield sheds rain at speed and resists the hard water spotting that makes RV glass so difficult to keep clear. Fiberglass caps, which take the heaviest ultraviolet load on the vehicle, are arguably the highest value panel to coat. We also coat wheels and painted metal trim where it makes sense, and we mask off rubber, unpainted textured plastic and roof membrane, which coatings are not intended for. ## Coating, sealant or wax on a large vehicle Carnauba wax looks warm and rich and lasts weeks. On a car that is a reasonable trade. On a 40 foot coach, waxing is a full day of work for protection that is gone before the season is. Very few RV owners keep up with it, which is why so many rigs are chalky by year eight. Synthetic sealants last longer, several months in this climate, and they apply faster by machine. They are a sensible middle option for a vehicle that already has a healthy finish and an owner willing to reapply once or twice a year. A ceramic coating is the one that actually fits the vehicle type. Applied once, properly prepped, it carries through multiple seasons and eliminates the reapplication problem entirely. The up front hours are real, because the correction underneath is real, but on a large vehicle it is the only protection strategy most owners will realistically maintain. The published range on this page reflects a correct process, not a wipe on product applied over unprepared paint. ## Living with a coated vehicle Wash technique matters more after coating, not less. Use two buckets, a clean microfiber mitt and a pH neutral soap. Skip automatic truck washes with brushes entirely, since the coating resists chemicals but does not resist a spinning brush loaded with grit off the last vehicle. Rinse from the top down and dry with a blower or clean microfiber towels rather than letting the vehicle air dry, especially with the hard water common through the San Gabriel Valley. Do not apply wax over a coating. It does nothing useful and it dulls the hydrophobic behavior you paid for. If the coating starts feeling less slick after a couple of years, the correct move is a maintenance product designed for coated surfaces, or a decontamination wash and a topper coat. Keep the coating away from the roof membrane. EPDM and TPO have their own chemistry and their own treatment products, and coating chemistry is not designed for them. We mask the roof edge accordingly. If your rig also needs roof work, sequence that before the coating so nobody is walking a freshly coated cap with a caulk gun. ## Frequently asked questions ### How long does a ceramic coating last on an RV parked outside year round? Expect meaningful protection across multiple seasons with correct maintenance, less on a rig that sees harsh chemicals or brush washes. Inland Los Angeles County is a hard environment: relentless summer ultraviolet and hard water are both working against the coating. Washing with pH neutral soap, drying rather than air drying and staying out of brush washes are what determine whether you get the long end or the short end of that range. ### Can you coat my motorhome right after you repaint it? Not immediately. Fresh urethane clear keeps releasing solvent for weeks, and sealing it early traps that solvent and produces dieback, which is a dull haze that shows up after you have already taken delivery. We wait 60 to 90 days after refinishing before coating. We will give you the date at pickup and hold the appointment so it does not get forgotten. ### Is a coating worth it on an older gelcoat travel trailer? Often more worth it than on a painted coach. Gelcoat oxidizes faster than clear does, and a coated gelcoat surface stays glossy far longer between corrections. The catch is that gelcoat needs more correction beforehand and consumes more product, so the job is larger. If the gelcoat is chalking heavily, the correction underneath is what you are really buying and the coating is what protects that investment. ### Can I still wash the RV myself after it is coated? Yes, and it gets much easier. Two buckets, a clean microfiber mitt, pH neutral soap, rinse top down and dry with a blower or clean towels. Stay out of brush washes, since a coating resists chemicals but not abrasion from a brush carrying grit from the previous vehicle. Do not add wax on top. It dulls the hydrophobic behavior without adding protection. ### Do you coat the roof of the RV too? No. EPDM and TPO roof membranes have their own chemistry and their own treatment products, and ceramic coating is not designed for them. We mask the roof edge and coat the painted or gelcoat surfaces, the fiberglass caps, the glass and, where it makes sense, the wheels and painted trim. If the roof needs attention, sequence that work before the coating appointment. --- OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887. Phone (949) 799-3387.
