So now that we've spent quite a bit of $ and time on our 97 LC that we purchased in August, I'm feeling even more motivated to ensure that it has a long and healthy life under our ownership. The underside of the LC has what I would guess is a fairly typical amount of surface rust on some parts, as you would expect from any car that is 25 years old. I don't want to spend a fortune (but am willing to invest) and without a lift, this is not something I'm planning to do myself, so just wondering if there are specific places out there that will take off surface rust and then put a protective coating on the underside of a vehicle? Would that be a body shop? Not really even sure where to start for that kind of service. Even better, if you of a shop in the Bay Area of Northern California that you'd recommend, let me know. Thanks in advance.
