Repair firewall rust holes

[84 c10 o skool]

Wanted to get ya'lls advice on how to go about reparing holes in the firewall.

I have 3 spots on the firewall that has holes due to rust. Water came through the cow past the old hard sealant. I will post some pics as soon as possible.

the largest hole is about 1"-2" wide X 4" long.

Thanks

Gotta be some big holes if they got past that cow.


So are you concerned about looks or just the functionality? If you're not concerned about pretty, just cut the bad part out. Find an old hood, door, bedside whatever you get access to, cut out a patch. Add some sealer lay the patch over the hole and a couple of self tappers and call it done. If you want pretty, just use the sealer and push the patch on. Then cover with a thin layer of Mesican Playdoh then sand smoothe and repeat as necessary.
