I'm currently looking at buying an entry level Class A. I'm looking at the Forest River Georgetown and a Fleetwood Fiesta/Terra. The Fleetwood has full body paint but the Georgetown doesn't. I talked to a lady at the dealer last weekend who was buying a new RV because she was disgusted that her fairly new RV was already yellowing. I've seen at least one post which said that all white gelcoated fiberglass will yellow, now matter what you do. I've also seen a post which says you just have to take care of it (no details). Does waxing help? What are your opinions?
I've been using NU Finish in the Orange Container for 5 years. It's not a wax but a treatment. I use it on my autos, boat, and fiberglass RV. It lasts for a full year. Black streaks just wash off with mild soap (Dawn). You can buy it at Wal Mart for about $6.00.
