Oxidized/chalky sidewalls on motorhome

The new to me Itasca sidewalls and front and rear caps are highly oxidized, chalky looking and the finish has a flat look to it, with no gloss. I took a small section on the back and used a little wax and an orbital polisher, and was surprised how good it looked. Huge difference, though it appears that I won't be able to make the decals look any better.

What type of wax should I use on a Itasca Sunova motorhome. (Might be fiberglas or gelcoat, not sure, and don't the difference between the two.)

Also, what type of polisher or buffer should I use for the best results for a high gloss? Should it be a orbital polisher or a high-speed buffer? I know that a high-speed buffer requires more care against automovtive paint.

Thank you, RTegarini

Polishing the bus!

On our old 1990 Itasca we used a polish and orbital polisher on her and she shone in the moonlight! Lol! Then I went over the decals with a fine cut polish and that brought them back quite a bit! Good luck!

I highly recommend the Fiberglass Restoration System from Maguiar's. It's available at marine stores like West Marine. It's also available online.

This is a 3-part kit with an oxidation remover (takes off the heavy, chalky surface), a polish (brings up the shine) and a wax (protects). I used it on my fiberglass roof. It wasn't real bad, so it didn't take very much elbow grease. The more oxidized the surface is, the harder you're going to have to work. If it's real bad, you may want to look into an orbital buffer.

What is a fine cut polish? What brand did you use?
