2003 fiberglass TC not looking so good …now what?

My 2003 BigFoot truck camper is all fiberglass.

The exterior has really started to denigrate… (when it rains the windows get white steaks from the chalk like fiberglass powder runoff)

I see so many wax type products advertised. Would like to know if anyone can offer a recommendation as to how to get it cleaned properly and what wax or other product can I apply to improve the appearance etc…

Thanks a million!
  • Wow! That’s is interesting. Will definitely look into that. Thank u

Prepare the entire surface, then apply several light coats of Zep acrylic floor finish. You should end up with a decent shiny finish that will last for years with minimal upkeep.

    Any autobody or marine compound and polish will work about equally. It’s all basically the same thing. The same 2 quarts of 3M compound and polish have done paint (urethane or acrylic enamels, lacquers), gel coat, filon.
    Unless it’s completely burned up and doesn’t have any competent gel under the oxidized stuff I couldn’t imagine going through the cost of painting it, when a cut and polish will bring it back to original condition.
    Yes, a new quality urethane enamel clear coat over base coat will likely last longer than the gel if not maintained again. But 5 grand minimum for a quality spray job vs a couple three hundred even if you have to buy the polisher pads and material…idk.
    Even if you can’t do it yourself you could likely get it fully cut and polished for well under $1000.

  • If you really like it. Have it painted. Use a good sealer on the fiberglass and then whatever color for the paint. Wax will only last for a short time then it will go back to being chalky.
  • Rotary polisher and heavy cut compound followed by the same with polish. Although it’ll probably look so much better after compounding you may stop there.
    Then I e heard that Zep floor polish works good for preserving the shine. Couple different camps on that stuff and I haven’t tried it myself yet.
