RV Repair Manual
for the RV Do-It-Yourselfer
The exterior finish of your RV is under continuous assault from the sun, rain, bug splatter, and road debris. Oxidation is a natural degradation process that attacks glossy paint and gel coats, leaving behind a dull, chalky surface. This chalking is the paint or gel coat breaking down due to UV radiation and environmental exposure.
Wash the exterior regularly with specialized RV wash and wax formulas. Avoid dish soaps or harsh household detergents, as their alkaline or acidic pH levels strip protective wax layers and dry out rubber seals. Apply a quality automotive or marine paste wax at least twice a year to maintain UV protection and water beading.
Installing a set of heavy-duty tow vehicle mud flaps significantly reduces paint chipping caused by road grit thrown back onto trailer sidewalls. Full-width brush splash guards mounted to the rear bumper are also very effective when paired with mud flaps. If you frequently travel on gravel or dirt roads, consider applying a rubberized rock guard or installing a trailer rock guard shield across the front lower section of your trailer to prevent permanent gravel pitting.
Maintenance Tip: Whenever washing the exterior, inspect all roof lap seams, window frames, and side molding seals for cracking or gaps to stop leaks before water enters interior wall panels.
