I swung by Harbor Freight (realize it's cheap tools but it was on my way back to work after dropping off parts). Sand blasting would cost a bit more, but I'm sure the end result is better.

I'm not certain my little pancake compressor has enough oomph for the siphon blaster attachment they had ($25). A big bag of aluminum oxide was $45. Assuming I could get by with my compressors, that's not a terrible investment I suppose.

I bought a 60 grit flap wheel for $4 and I'm going to see how well that does. Between that, the wire cup brush and a standard wheel wire brush, I think I can hit a majority of the tight corners.

We shall see!

That flap disc will do well, perhaps just sandblast the inside corners where you can't get to with the other tools. Your little compressor should be fine for a few small spots. But once it's stripped, get it coated asap with something. A 2 part epoxy primer would be best. That raw exposed metal starts to rust virtually the same day you strip it. Aerosol can crap won't seal that coarse raw steel up well and it'll start rusting again very soon, maybe even within a week. You can get a cheap paint gun for 30-40 bucks. I recommend a gravity feed with a 1.4-1.8 tip. You can get epoxy primers at any auto paint store like Sherwin Williams, napa, autovalue, etc. It varies in price, cheap stuff is fine.

10 cent dust mask, ear muffs that double for hunting season, and some goggles. I'm set :D

I assume I need to clean the service first to get the dust off? It can't be as simple as wiping down with alcohol I suppose...

Use a blow gun to remove the dust, then a rag with alcohol or wax n grease remover. I usually just use a blowgun because a rag will snag on the rough metal and leave fuzz n shit on the metal.

One med-heavy coat of epoxy, then 2 coats of you desired paint.

problem with boat trailers is there ain't no way you can get at the inside of the tubing. i can only assume that there is some degree of rusting from the inside out. no?

When I restored my boat trailer I used a long tube sprayer to coat the inside with rust Mort, a type of acid that converts and seals the rust.

Oh yes. Inside of metal is plenty rusty. When he built it, he neglected to account for drainage. One of them actually expanded and cracked from ice over the winter. I'm going to drill out drain holes on the four main metal supports so that doesn't happen again.

This truly is more of a utility trailer that doubles to hold a kayak/duct boat. So it's never been submerged, but it does get wet.

If you have a good power washer they clean a trailer really good. I have a gas powered one and can peel the paint off a truck if not careful. I have 4 nozzles and always power wash the trailers before I paint them. I have had very little peeling after painted.
