[censored] GM and their fit and finish.... Anyways, I've been cleaning up my cars, and my wife' Cavalier(03) is getting some rust under the doors (on the inside). Which is sad because the outside of the car still looks quite good (it gets a good waxing next week). I was thinking about just sanding it down, putting some Por on it, and call it a day. I guess I'm lucky, beacuse these are the only places with rust. I don't plan on spending truckloads on money here, but I do not want the doors to get worse either. All this while trying to keep it shiny too. Any good ideas that I could use?
