polish

I have a fiberglass/gel coat TT. I used Meguiar's Flagship Premium this last weekend and WOW the shine, almost mirror like! It is the easiest to remove wax I've ever used. It's pricey though.

REJEX is what I use. Goes on easy and comes off the same. Its great stuff

I've used Nufinish in the past and it seems to work well. Basically anything you would use on your car is fine.

I like the Mequiars Ultimate paste. It ain't cheap but it is very easy to use and seems to work well.

Is your RV metal or fiberglass? Some people use a marine polish if fiberglass.
