I'm mainly interested in seeing what folks did to restore the gel coat on older units.
Lots of information about that here. You'll find four general schools of thought on gelcoat restoration. All start with a thorough cleaning and removal of oxidation.
- Automotive or marine paste wax.
- Liquid floor wax.
Door #1 is best on a newer trailer. On an older unit it will protect, but it won't give a like-new gloss. It has to be reapplied regularly (how often depends on climate and storage). Door #2 gives a high gloss shine and can last through several seasons, but will eventually peel, requiring removal before reapplication. Door #3 requires use of the right paint
and technique, since fiberglass flexes. It's usually reserved for situations where there are fiberglass repairs that don't match the original gelcoat.
I use an automotive wax twice a year. When I bought my trailer, it was 4 years old and probably hadn't seen a coat of wax. The results of the first few waxings were spotty, but it's gotten better with repeat applications. Warning: even on a small trailer like mine, it's a workout!
You can pull up lots of old threads with specific product recommendations using the Google site search. From the website, go to the blue bar at the top under your log-in information, "Search," and all the way down to "Site search/Google."
Oh yeah… the fourth option. Just let it age. Gelcoat is only cosmetic, and a dull trailer is less likely to attract the attention of a thief.
