You guys have been an invaluable help for an inexperienced mechanic like myself. I appreciate your time. After lifting the carpet and foam, I noticed a very small hole surrounded by rust on the drivers side floor pan. I have seen replacement floor pans for sale, but I imagine this involves pretty serious welding and body work (maybe not, does it bolt in?). I'm not tearing this car down and restoring it. With that in mind, what's the best way to deal with this? The car now resides in a mild climate, and is garaged or covered in the winter. Can I let this go and apply some sort of agent that deals with the rust? Does this rust and hole mean that further deterioration is inevitable, and could possibly spread to other parts of the car? Sorry if these are naive questions. Many thanks.
