Okay we've talked about gliders now lets talk about trailers I have a cobra

1984 all aluminum chalking up needs and needs to be refinished what
would you use and do you need to prime. There is no peeling just severe
chalking the current plan is too sand for a tooth an wipe it down before
applying a one part auto paint. Any other suggestions? I have never
painted before so am open for suggestions.

Thanks
