Surface rust questions

[justletmein]

Got an old buggy that's headed to an island on the coast to finish it's life out, so it'llbe in a pretty corrosive environment. I was gonna hit this stuff with some rustoleum or something but figured I'd ask for advice here to see if I can do better.

I would clean and treat with Ospho first before painting.

Same here. Ospho is some good stuff.

I'll look up Ospho, thanks! I actually remember the seller mentioning it and couldn't remember exactly what he said.

knock off loose stuff with wire brush, then hit it with ospho using a paint brush. Believe you gotta wait 24hours before primer and paint.

Ospho is awesome stuff!

When I lived in town I had a neighbor that was a bit ****. ( A good friend) I had a BBQ pit that was a bit rusty. One day I came home and He was spraying my pit trailer with Ospho. To this day 15 years later where sprayed is good. I treat all my stuff with the stuff now. It’s good stuff.

Worked on a rusty trailer frame today, I like to pressure wash,wire wheel, ospho, and then paint with that cold galvanized stuff.

REMOVE ALL VISIBLE RUST...then prime and paint. I worked for a metal finishing company (electropolishing steel). We had a lot of equipment that we beat the heck out of and drug all over the world. We had severl pieces of heavy and valuable equipment that we built heavy duty protective frames for, these frames were all carbon steel. We nock off all rust using 8 inch flap wheels, if it is really bad use a wire brush (your pictures arent bad at all). Once it is done, quickly apply rustoleum primer (carbon starts to oxidize instantly). We usually put two coats of primer on then paint. We've had equipment shippied from houston to france to toronto to japan then back to houston all via ocean freight and all being exposed to phosphoric and sulfuric acid during our process and never have issues with rust.

How does Ospho compare to Gem Rust Killer?

I have an old trailer that I’m looking to rehab and have a good amount of Rust Killer I had planned on using but if Ospho is much better I may reconsider.
