So I live up in Canada, and it's winter now. This means salt on the roads. A terrible reality for a protege driver. The guy that I bought my car from did some bodywork on the hatch, in the spots common for rust, as well as on the rear wheel wells. Unfortunately, it has started to rust again in the rear wheel wells. Also I have noticed that all the doors (except for the rear passenger) are getting really rusty at the bottom too, but I don't know if you can do anything with that without getting a new door. The undercarriage of the car is not terribly rusty at all, and overall, the rest of the body and paint is pretty good. I love this car, and I want to fix the rust before it's too far gone but I have no freaking idea how. Also I bought the car with a massive dent on the rear passenger side. And a few other dents around. So my plan is to do some bodywork at some point this winter. I will include some pictures and if you guys could give me some suggestions on what all I would have to do to fix it that would be awesome.
