Welding trim holes on 1970 Dart

I did the other holes by taking a 3/8 drill bit and just counter sinking the edge of holes for something more for the weld to bit to. I did one of the quarter panel holes, it came out well but then got nervous about the body line. I am not to worried about the warping because I have been just zapping a little and moving to the other end of the panel regardless if the hole is filled or not. Once it cools, I go back and tack another. The welds are solid, and no seem once ground down. I will take some pics.
**Note** do not use a grinder, too aggressive. Stick to a wizzer wheel type of airtool

Thanks for the compliment, Carnut.

72bluNblu, there are holes only on mine, because the trim is bolted on. I have no trim studs at all on the 70 Dart
