My 70 Dart

First pics from drivers side. Before mud and after mud and sanded. I'm wanting to remove the panel line. Guess I'm lazy, 40 year old car, seams don't line up like they should. I don't have the time, knowledge, or money to do it the right way. So I cheated and use as little mud as possible. I know the mud could come out if hit hard. Well, if that happens my feeling is mud popping out will be the least of my worries. Thanks for looking.
