I live in bright and sunny Southern California. The sun is relentless and will eventually fade and oxidize all fiberglass if you don't stay ahead of the damage. Anywhere you find an RV storage lot in Southern CA you will see an ocean of white, (and now tan and grey late model), oxidized fiberglass!!

There is one fantastic remedy for newer fiberglass. If your RV or boat is less than four years old and the gel coat is still intact. It's NOT the typical compound polish and wax routine. Been there, done that.

It's 303 Aerospace Protectant.

It's not permanent, and it only lasts for a few weeks at a time, (hmmm, just like at a dealer lot). But it will restore late model newer fiberglass under four years old. And it's really easy to spray on and use a microfiber mop once you get into the routine.

Just spray it on the clean oxidized fiberglass. Let it soak in. Wipe off before it dries. Repeat until the surface is glossy and reflective again.

About a decade ago there were videos showing 303 Aerospace protectant being used with a buffer. You might be able to find the guy restoring a boat's gelcote. If you spray it on wet and use a buffer as it dries, the results are even better.
