I've got this older 20ft 1986 Wells Cargo trailer that i really like. The under side is solid but the factory paint is gone as is the bottom inch of the alum sides, from Galvanic corrosion. I'm going to be putting new axles under it as one cracked coming back from bike week. The plan is to put diamond plate on the lower 6 inches of the sides to make it look clean again. In the past I've used POR15 but the last few times it's not lasted like it used too. for example in 1980 i painted the inside of a 65 ford pick up bed and the engine bay with POR15, as of 2 years ago when i sold it you could still see the paint in the bed and the engine bay looked like it was just done. I've used por15 on other projects since then with less luck. It's never let me down but isnot the same as when i did the pick up. I see adverts for RUST BULLET and MasterSeriesCT but what works best? Not top planing on a top coat unless i have no choise.

I'm watching this thread because I have a chassis that will soon need to be stripped/painted. I'm interested in seeing what other responses you get.

All I can offer is a hypothesis. I was recently told that POR15 worked, but that it didn't have UV protection, and that it would break down if exposed to sunlight. Perhaps they've changed the formula, and what you used earlier didn't have this problem.

In this thread, 914Driver said, "House of Kolor makes Adhereto, sticks any paint to anything." Perhaps you could use POR15, Adhereto, and then a different paint to protect it.

I've used rustbullet and will continue to do so. Its a great product and it works well.

Ive heard good things about Masterseries as well but I have no personal experience with it.

I'll second rustbullet. Its thick and smelly, both positive attributes for a product meant to stick and seal. Plan to buy enough for two coats.

Bill Hirsch Miracle Paint.

We use it at work, great stuff, water thin, flows into every nook, cranny and pit you can find.

Sprays well without thinning but you need to topcoat it because it has no UV protection.

I've had good luck with Eastwood Rust Encapsulator. It's less toxic than POR15 and is UV stable.

I bought the Eastwood paint when it was called Corroless. It was awesome.

Ya know, that cheap nasty rustoleum rusty metal primer, thin it about 50/50 with acetone, and it soaks into the rust and metal, becoming virtually indestructable.

I will only use the "black" rust bullet... the silver worked ok but the black is really the best. Do not get this stuff on your skin!
