removing undercoating/rust 1979 300D
I was wondering what the best way to remove stock undercoating is for the at home mechanic?
Also, I seem to have a pretty large rust problem. I have Miracle Paint and would like to attack it from top and bottom but it seems like one of the screws holding down my passenger seat is rusted to the body. How do I get it out? Of course it's the right rear screw, the hardest to reach to begin with.
