I was wondering what was the best way to go about fixing this cancer. The rusty part (what was rusty) wasnt that bad, but the previous owner had it bondo'd before i received the car. Now the bondo is cracking, so i thought i would check on here to see what is the best way to take care of this, that would be a good fix. The black spot is where the rust was on this side, only about a 5" by 1/2" rust hole. Thanks
