Grand Design to Forest River XLR......need advice....

Work and Play are metal (except the new Catalyst line), kind of like a snowmobile trailer or other enclosed cargo trailer. While they are technically painted, that is not the same paint or finish as a fiberglass trailer with automotive basecoat/clearcoat applied. While FBP fiberglass trailers still need wax just like a car that lives outdoors, they don't fade like a sled/utility trailer.
