# Ceramic Coating: Cost, Hours and Process in Hacienda Heights Ceramic coating applies a silica based liquid that cross links into a hard, hydrophobic layer bonded to the clear coat. On an RV its real value is UV resistance and reduced wash effort across a very large surface, not scratch immunity. It locks in whatever finish is underneath, so correction comes first. ## Specifications - Price band: $800 to $3,500 - Shop hours: 5 to 20 hours - Turnaround tier: Light cosmetic - Insurance billable: no - Parts lead time: Coating systems in stock, no lead time - OEM brands: Gtechniq, XPEL, 3M, Sherwin-Williams ## What a coating does and what it does not A ceramic coating is a liquid that cures into a thin, hard, chemically bonded layer over your clear coat. What it genuinely delivers is a high contact angle, meaning water sheets off rather than sitting; substantially reduced surface energy, meaning bugs, tar, tree sap and road film release with far less effort; and meaningful UV resistance, which on an RV parked outdoors in the San Gabriel Valley is the most valuable property of the three. What it does not deliver is scratch immunity. Coating hardness is measured on a pencil hardness scale that has very little to do with a branch dragging down a sidewall or a wash brush loaded with grit. It will resist marring from washing better than bare clear. It will not stop a scratch. For an RV specifically, the wash effort reduction is not a luxury argument. The surface area of a 38 foot coach is many times that of a car, most of it at a height that requires a ladder or a pole, and the practical difference between a coated and uncoated coach is often the difference between washing it regularly and not washing it at all. Coaches that stop getting washed are the ones that oxidize. ## Preparation is most of the invoice A coating is optically clear and permanent on the timescale of years. Whatever is under it is what you will be looking at. Swirls stay swirls. A water spot etch stays a water spot etch. Oxidation gets sealed under a glossy layer and looks worse, not better. So the sequence is decontamination wash, correction to whatever level the film budget allows, a residue removal wipe to strip polishing oils, a panel wipe with a coating specific prep solvent, and then application. The correction stage is usually the majority of the hours, which is why the band on this page and the band on the correction page overlap: a coating job on a neglected coach is mostly a correction job. Application itself is methodical rather than fast. The coating is laid panel by panel in small sections, allowed to flash to the point where it hazes, then leveled with a specific towel sequence. Leave it too long and it cures high, which means machine removal and a second application on that panel. On a coach sized surface that discipline over hundreds of square feet is the skill. Then it cures. The coach stays inside, dry, out of dew and sprinklers, typically 12 to 24 hours before it can be moved and considerably longer before it should see rain or a wash. - Chemical and mechanical decontamination - Correction to the level the measured film budget allows - Polishing oil removal and coating specific panel prep - Sectional application with a controlled flash and level sequence - Second layer or topper where the system specifies one - Indoor cure window, 12 to 24 hours minimum before the coach moves - Maintenance instructions in writing, because coated paint is washed differently ## Gelcoat, film and the surfaces people forget Coatings bond to more than clear coat, and on an RV that matters. Oxidized gelcoat can be cut, restored and then coated, and on a fiberglass coach that combination is one of the more effective things an owner can do, because gelcoat chalks under UV and a coating slows that meaningfully. Glass gets coated on the windshield and the driver side windows, where the hydrophobic effect has a real functional benefit in rain. Wheels get coated because brake dust releases far more easily from a coated finish. Vinyl wrap and paint protection film both accept coatings designed for them, and coating a wrap is a sensible way to extend the life of an expensive graphics package. What we do not coat is a surface that is actively failing. Peeling clear, lifting film and delaminating gelcoat all need addressing first, and on delamination that is fiberglass work, not paint work. ## Not included - Coating cannot be applied at a customer location. It needs a dust managed bay and a controlled humidity and temperature window for cure. - We do not coat over uncorrected defects, failing clear or oxidized gelcoat. Whatever is under the coating is locked in. - Freshly refinished paint is not coated on delivery. The clear needs roughly 30 days to finish cross linking first. ## Questions **Is ceramic coating worth it on an RV?** For a coach stored outdoors in this region, usually yes, and for a reason owners do not expect. The value is not gloss. It is UV resistance and the fact that a coated coach is dramatically easier to wash, which means it actually gets washed. Coaches that stop getting washed are the ones that oxidize, and oxidation is what turns a detail bill into a refinish bill. **How long does a ceramic coating last on a coach?** That depends on the system, the surface it went onto and how the coach is washed and stored, and honest answers are ranges rather than numbers. What we can tell you is what degrades it fastest here: automated brush washing, alkaline truck wash chemicals, and sprinkler mineral deposits at a storage lot. We provide written maintenance instructions because coated paint is washed differently. **Can you coat my RV right after you repaint it?** Not on the same visit. Fresh clear continues to cross link and out gas for roughly 30 days, and sealing it under a coating during that window interferes with the process. We book the coating as a return appointment about a month after the refinish, which also gives the finish time to reveal any defect worth correcting before it gets locked in. **Do I still need to wax a coated RV?** No, and you should not. Wax and traditional sealants sit on top of the coating and mask the hydrophobic behavior you paid for. Maintenance is a pH neutral wash, a coating safe drying method, and periodically a maintenance topper designed for the specific system. Brush washes and alkaline truck wash soaps are the two things to avoid. **Can gel coat be ceramic coated?** Yes, and on a fiberglass coach it is one of the better combinations available. Gelcoat has to be cut and restored first, because coating over chalked gelcoat seals the chalk in. Once the pigmented resin is brought back and the surface is prepped, a coating slows the chalking that caused the problem in the first place. --- Source: https://ocrv.club/rv-paint-shop/ceramic-coating OCRV Center, 23281 La Palma Ave, Yorba Linda, CA 92887 Phone (949) 799-3387.
