I have a '72 240z which needs paint and minor body work. The question I have is concerning Bondo and the effects it has on the value of the car. I understand large areas of Bondo are not good, but is it acceptable to use Bondo on door dings approx. sizes ranging from 1/16" to 1/2" in diameter? The other question I have is: Does anybody know of a trustworthy automotive shop/mechanic in the Houston, TX area that can "refresh" the engine and auto transmission? Any info would be great! Thanks, Bill
