303 application

I use it on every square inch of my boat, inside and out, and on the tires, dash, and leatherish seats in the MoHo.

The wet-suit seat covers in my old jeep came with a bottle of it to spray on the seats to protect them.

It does a good job of protecting the stuff from the desert sun, dries to a nice shine, and isn't sticky after it dries.

That was nice. It is a UV protection. :)

Yep that's the stuff :)

is this the stuff you're talking about?

I use it on canoes and kayaks, makes them very slipery and fast.

Thanks folks I knew I would get the straight scoop here!

303 is actually not a wax or really meant to be used like wax. It is a UV protectant and is good on fiberglass, vinyl, rubber and plastics but not so much on painted surfaces, so I can only assume your camper shell is unpainted fiberglass (technically it would be resin gel-coat). If it improved a painted surface, good, but not its best use. Multiple applications could help if the surface is really dry and oxidized.

I like it best for interior vinyl surfaces and plastic lenses.

No benefit if the first wipe looks good. Too much will cause white streaks when it gets wet...go easy with the stuff. :)
