I use the same product on my rig along with a D/A polisher hope this is of some help to you.

That may be the case on unpainted gelcoat rvs, but the painted RWs are painted with automotive base coat/clear coat same as your car/truck, so any automotive polish/wax should not yellow or harm the finish.
The marine type won't hurt it, but an unnecessary expense.
I've used Turtle Wax Ice for the 6 years we've owned ours, inexpensive, easy to appply just spray & wipe & holds up nicely for the 6+ months til it's time again.
