bodywork question

[DecoyOctopus]

its bigger then a screw. a 10mm bolt fits in there perfect. but dude i cant get to the back to weld anything and i know that cant be the end of the story.

You weld the hole up, from the outside. No need to put anything behind it.

lets say i got some holes to fill up. i cant get to behind the holes and like weld something to the panel to give the body filler something to hold on to so how would i go about doing this. any tips tricks?

Assume you're shaving molding? Welding is a bad idea if it's a car built in the last 25+ years with thin sheet metal...not saying it can't be done but without keeping the metal at precisely the right temperature its going to be wavy beyond repair.

He has a very good point I didnt even think about. You need to be damn good or you will destroy the panel like he said.

Yah, heat will cause the sheet metal to contract at the welds and then you end up with a door that looks like corrugated metal roofing

When he says damn good he's mean practically TÜV certified.

Mine...
