Finally got a Dart!
One must realize, that you are working on the underside of the car. There are some great products for sealing the patches. About the only thing I would change, would be to add some additional welds to the seams, (it should look like stitching). When was the last time you went to a car run, and saw someone laying on their belly, to look at the underside of a car. The main thing, is to get a driver, that will turn a few heads, and have some fun. Good luck. Howard
