Painting a trailer

Will have to clear any loose paint, and scuff the surface of the rest or will not stick for long..

Thanks. Had not thought about a palm sander but had considered an angle grinder with a wire wheel on the painted area. A palm sander would probably be safer as that wire wheel will kick back sometimes. Just wasn’t sure if sanding/brushing was necessary. I like the rust-o-leum red oxide primer for rusty metal just wasn’t sure if it would be good to use on the areas that still had paint or if I needed to use something else. Thanks again for the help.

I first use a needle scaler to remove anything loose, then sand it. I blow it off with compressed air and wipe it down with Preps-all. Then I use Rust Reformer | Rust-Oleum over any spots with visible rust. Let the Rust Reformer (or Rust-Converter) dry, prime with a primer that is compatible with the paint I am going to use. Lightly sand again, blow it off, another wipe down with Preps-all and paint. I lightly sand, blow and wipe between paint coats.
