Is it gelcoat all over or is it the finish where you can still see the chop strand in the panels?
If the chopstrand type no amount of waxing will give a gloss. Stuff like formula 303 will rejuvenate it.
If gelcoat it should not be too bad provided it has not spent all of its time in the blistering sun & never been waxed. In any case treat it like a boat. You might get away with something as mild as a cleaner wax like 3M marine cleaner wax followed by a pure wax or sealant type for a long lasting shine. If chalking is bad there are various grades of compounds. Be careful. Use the minimal agressiveness compound to get the results needed. RV gelcoats tend to be very thin.
I'd love to paint mine but to do it right would be cost prohibitive. Currently, like so many, it is a brilliant white. A huge box freezer with wheels. Given wads of money I'd have it redone in something off white, using a marine epoxy paint like Awlgrip, painted graphics (nothing too wild) & a couple coats of clearcoat over everything.
I'll keep dreaming. Rig is 6 years old, gelcoat in excellent shape, waxed every year before season with Mequires Flagship & spends 7 months indoors.
The only thing I can see happening as long as the gelcoat is in good shape is replacing decals, this time with a better quality marine grade material. RV builders use stuff as cheap as they can find. It takes the same labour to apply cheap material as good stuff. Might as well get the good stuff & have it last longer.
