i would assume welding in some kind of patch but the holes are so small? i saw someone on here fill in the hole all with wire but that would make the door so hot and most likely warp??

 

just use duramix 4179 or the proper setting formula.

patch with sheetmetal and bond. simple.

no welding. bonds and seals really good.

ps. make sure you get the right application gun and alot of tips.

 

i am searcing on google for duramix, with the moisture and temperature changes does this stuff swell up or pop out at all? i try to use a small amount of filler as i'm sure you do too, just wondering if you know this stuff works good from first hand experience?
