What's the best process for filling these holes? I suppose many have just filled with plastic filler, but I want to do something more permanent.

I've been thinking about placing large-headed steel nails through the hole from the inside and brazing them in place and using a cutoff wheel to remove the nail shank.

Is there a slicker way?


You could braze them but you might warp the bejesus out of the panel. The best way is to mig or tig weld them shut for a permanent solution. If you do a little at a time and move around to different holes you wont warp the body panels. Depending on the diameter of the holes I have also used a nail gun for pulling dents to "weld" the pulling nails in place over the hole and simply grinding it down flush with the panel, seen lots of guys do this to works great.
