removing dull haze from fiberglass?

Our trailer is a 2005 fiberglass and is a case where the inside was better than the outside. I suspect it has some sort of sun damage. Underneath the license plate and on 1 side, it is still shiny. The rest of the fiberglass is fairly dull. No black streaks.

I have tried to search on this forum and saw the suggestion for Lemon Pledge and bought 4 cans at Costco. It did not really remove the haze.

Is there another product to use? Is there some type of buffing that could be done? Would this harm it? Any other ideas?

Thanks for all the help!

On my boat I used 3M Marine Cleaner and Wax, gets rid of the oxidation and lays down a coat of wax so the water beads right up.

You want something that will remove the layer of oxidation on the gel coat. That can be a marine product, a cleaner or a cleaner/wax. I've had really good luck with Jasco Prepaint Cleaner. It is a TSP substitute sold at the big box stores in the paint Dept. I dilute it and spray it on surfaces with a tank sprayer. Brush the surface and rinse.

Rubbing compound an orbital buffer and lots of work. Followed by quality boat wax
