I always liked those Casitas, Borros and Scamps.

It's gelcoat no different than a boat hull. The enemy of gelcoat is UV. The best thing you can do is keep it out of the sun and protected.

If you have minor oxidation a quick polish with something like Nu-finish then followed up with a few coats of a good wax or polymer with a UV protector.

Heavier oxidation will require more compounding/polishing then wax or polymer.

You will want to get a nice build up of wax/polymer on the surface. If you can try and wax/polymer every few days for a week or so. Get four, five or six layers built up. Also avoid using any detergents to clean that would strip the protective coatings you are applying otherwise you are doing work for nothing.

As I said in the beginning keep it protected from UV under a cover, in a garage or at least in a shaded area.

Personally I am still a Carnuba wax kinda guy for my gelcoats and paint. My rubber and plastic parts I like 303 protectant.
