Location: Lyons Oregon | How do I clean and preserve the fiberglass top on my trailer? It is "grungy" with dark gray gunk mold-like stuff. I found a product that cleans it beautifully "Superclean by Castrol" but it also stripped the paint from the pretty teal stripe. Luckily I had only done a small section. Would a powerwasher work or would that damage the fiberglass? And should I coat it with anything when it's clean? So far I've just washed it with carwash soap. |
