I have yet to use any ceramic coating products, mainly because I haven’t clay barred or finished polishing the vehicles or toys that I want to use it on.
From what I’ve seen and what I understand, it works well. It. An be used equally on automotive paints, acrylic and urethane enamel and on gel coat (fiberglass boats and your camper)
If you just got it polished, this is the time to do it.
It is also not a super technical application and if you are at all adept to paint finishes, you can do it yourself.
Do some reading on it. Fwiw, it costs about $100 in materials to do the camper.
It is supposed to offer UV protection as well as repel water (obviously)
If I had the time and the need it would’ve something I’d do
