Rust and rust hole repair. Can you tell me what grit sanding paper or wire wheel I will need to buy for this? I would like to make just one trip to the parts/hardware store and just settle in for the long grinding/sanding/patching/spraying and painting process. I know, wishful thinking, but I can always hope.

it's actually better to buy a few, from relatively heavy duty to really fine, so you do the best job

you got it. I'll send before and after pictures if I can pull it off. Take care and thanks for answering my question.... again!
