[QUOTE=gordon2;636119]Mind if I pose a related question to the group?
Assuming that one has a FG trailer in good condition, with little or no oxidation to the
fiberglass body finish, which product would be better for a trailer that is stored outside in the southeast?
That would depend on what your calling "with little or no oxidation".
If it's indeed "little or no" a good polishing and then wax would be better.
The reason I say that is because some, not myself, have had Poli-Glo flake off and I believe that's from using it over a still decent slippery gel-coat.
Now if the finish is badly weathered like mine and no amount of polishing will restore any semblance of a shine then Poli-Glo or ZEP wet look floor finish will make it look like new after a good cleaning. (shiny black streaks still look bad)
After Poli-glow or ZEP has hardened for a day or so a coat of good wax will make water bead up on it and enhance the shine even more.
