Waiting for rust repairs.
What do you do with rust spots that you want to fix later. I've been grinding them down and using rustoleum primer. Is this dumb or is there a better way?

If fix them later is going to mean grinding down to bare metal or cutting out and welding in new then I say what you are doing is fine. There are better products out there ( POR15, Rust Bullet etc. ) but I wouldn't use them if you are going to grind/cut them away. But for the final repair I would.

1. Use a wire wheel on a grinder to get all the loose rust / oxidation off.
2. Treat the remaining metal with something like Ospho which kills the rust. But you're not done yet... 3. Paint the metal with quality paint. Not just primer, because primer is not going to seal it well enough to prevent rust for long. Use a strong rust-preventative paint. I like Hammerite which is available in spray cans as well as pints/gallons/etc. Others like POR15. |
