You can buff that til the cows come home. It won't last. The only real cure is to have it painted. I've had two fifth wheels painted. If you shop you can find places that will do it for around $1,000. Forget the RV dealers. Go to a big truck bodyshop.

Partly true, partly false.
True part is, if you just do a quick polish to gelcoat, you can get it looking decent and it won't last. If you do it right, it is essentially a new surface and will take roughly as long as it took the first time to oxidize and look chitty, again.
You and arcsum68 obviously aren't paint and body guys and are both somewhat mistaken.
