Best fiberglass cleaner?
we have a new trailer and and would like to get it good and clean, and wax it - so it stays clean longer and is easier to clean. planing to use a Resistall wax that the dealer tried to sell for $1,000 (with 5 year warranty), but I found online for ~$30.
there are already some black streaks showing up, which is kind of disappointing. the dealer said that the vinyl roof isn't supposed to streak "as bad" as rubber.
There are also some areas where you can tell they tried to clean some caulk smears off of the surface but didn't quite get it all.
