My car's paint is wearing off. I don't care about the cosmetic impact, but I'm worried about rust. What can I do myself (or have done cheaply) that will prevent further damage?
I'll be honest - I don't take stellar care of my car. I bought it used a few years back, and mechanically it's fine. I only wash it once a month or so, though, and have never waxed it or anything like that.
Over the past few months, I've noticed that some areas have lost their finish, and now the paint is starting to go. The surface in these areas is kind of pitted, where some parts of the finish have worn down more quickly than others. (See pictures here: 1
I'd like to fix this before my car's body starts rusting, but a full paint job is out of the question. I don't really care how the car looks. I just want to make sure that this car lasts for another 3 or 4 years, until I'm out of grad school.
Is there any kind of wax or sealant I can apply myself that will stop this erosion? Is there some kind of treatment that a body shop can do relatively cheaply? I know next to nothing about auto paint, so I'm hoping the hive mind can help me out here. Thanks in advance.
