Repairing rust spots on oil pan

[Dave M]

My daily driver, a 2000 Dodge Grand Caravan, has some rust spots on the oil pan. It's getting to the point where the pan is getting thin in these spots, and I want to stop the problem before the obvious worst case scenario happens. I don't want to have to replace the pan, so I'm hoping I can repair it. Would it be advantagous to sand the pan down and put some type of rust stopper/converter on the spots, like POR-15, and then paint the whole pan? I could do this while it was on the car. Has anyone done this before, or anything like it, and do you think it would keep the spots from getting worse and spreading or rusting completely through? The rust spots seem to be primarily on the front of the pan that collects all the road/salt spray. I'm thinking a light sanding with an application of a rust converter and then some simple rustoleum spray paint might do the trick.

Opinions?

Good question. Something I've always thought of but for some reason, never asked on these boards. I do my parent's oil changes, and my dad's taurus is looking like it might rust through.

I too would be interested in an answer to this if anyone knows.

I would just take a Scotch-Brite pad or some fine steel wool and a product called Metal Ready ,made by POR-15, to just remove the very loose rust. With the Metal Ready, you do not need to get 100% of the rust off. Let the Metal Ready dry and then wipe off the powdery residue with a wet cloth then let dry. Then you can just apply the "black" POR-15 paint right over the Metal Ready.
