How to remove oxidation before waxing?
I bought a used trailer that has been kept outside and I would like to cleanup the fiberglass walls before storing it in my carport. What is the best way to do that? Thanks, Griz14

The best way depends on a lot of variables. I don't know how anyone can recommend anything without knowing the details. How old is the MH and how bad is the oxidation? Will it come off with just hand polishing with a good compound wax after cleaning it good with the ZEP's process? If so you have your answer. If it won't clean up by hand how good are your shoulders? If good I would use a polishing wheel and a good compound. I have done this before I tore both shoulders on a really oxidized boat and it came out good with white FG and gel coat. Gel coat thickness on a boat hull will be similar to a front and rear cap on a MH .020-.040 ins. Side walls will be thinner. Does your trailer have full body paint? If so it should not be that oxidized and I would be real careful with a machine polisher using the smallest grit possible. My MH is 25 years old and I have two torn shoulders so when I could no longer hand polish about 10 years ago I did the Zeps process and every several years I reapply mostly to the front cap because it gets more wear than the side caps. I have never stripped it I just clean and reapply. My gel coat was really worn so it adhered well and has never yellowed. Still shines better than when I got it in 2004. Good luck with you project, hope this helps.
