Slightly rusting trailer, what paint?
Posted April 25, 2007 - 12:10 PM
I picked up a used trailer last night for a very good price. It is only three years old, but has some rust spots on it. Not too bad, very structurally sound. The rust areas make up about 2% of the overall surface. The entire trailer is steel, steel floor, steel fenders, etc.
Question - the rusted spots are small and very scattered across the whole trailer. Most are between the size of a dime and a quarter. There are literally hundreds of them though. The question I have is would a product like rust-oleum, or some other paint on product work to seal the rust and stop it from spreading without sandblasting the trailer, and without sanding all the individual spots?
What are your recommendations? I am not looking for a show trailer, just dont want it to deteriorate further.

What i would do for the rust is take a wire wheel or a wire brush and clean off a good area around the rust spot. If the rust shows then the moisture has gotten under the paint so it would be wise to clean up at least an inch or so around the rust spot so you can uncover the hidden moisture.

Thanks for the suggestions. The real question is this - the rust spots are small, but they are distributed all over the trailer. To attempt to sand or wire brush all of them would mean to strip the entire trailer of paint. Is there a product that really works that you can spray over the rust and the paint, and it will seal and stop the rust from spreading?

1. Remove all the rust by sanding.
2. Scuff up the rest of the paint.
3. Prime the bare metal spots with a quality primer like DuPont Variprime.
4. Paint the whole trailer with DuPont Imron two part epoxy paint.
This is generally what they use to paint heavy equipment, and frame rails for big rigs. Lasts a loooong time, but is not cheap. You'd have to go to an automotive paint supply shop to get it as well. If I remember correctly it's about $100 per gallon plus hardener. I used this method to paint one of my old cj-5 jeeps about 10 years ago (the whole body inside and out), and still not a spec of rust even with the massachusetts winters (SALT!).
