I would send for the Jamestown Distributors general boating catalog from
www.JamestownDistributors.com there are free tech support books regarding
fiberglass, a forum, and a whole load of stuff, they also have free phone tech help to ask questions from about materials usually guided toward
fiberglass boats, also they produce a 18.00 how to on
fiberglass tech. Which when you get to repairs is invaluable and a couple of 4.00 manuals available, also incl. with their services is free tech support so that you do not purchse materials that react with each other. (not all materials play well together) they are knowedgable about single part and two part urathanes and epoxies, and two part primers...adhesive removers which are safe to fiberglass tecnologies...The catalog is free and the website contains a part of the cataloge inventories...You really want the general catalog, there are two, the General catalog is 1168 pages and its free on 1st order, the first catalog they will send you free on request is a little one.
When you order even the free "how to stuff" or the DVD I use, which has three books on it about fiberglass repair for 18.00, you get the mother catalog with that order. Granted this is a boat catalog and some may scratch heads why I suggest it...However thats what you have only its on wheels, there are paints that retard mold and mildew growth not generally available except on the coasts regionally...Boats can have the same issues as fiberglass trailers...There are vintage trailer sites I have used too... This board has been an excellent contact place for knowlege for me...While I have read its forums for years only. I only recently surfaced as a name and registered here. I have found other trailer forums too...but not better or more open.
Hope it helps.
