I was out the other night poking at some rust and well... it turned into a good 4'' hole. Of course its the rear quater behind the tire where i poked through. I also have a matching hole on the otherside. BTW... I was putting some rust converter on the rust spots.. i don't just go around poking at rust on my car
. Anyway, Whats the best way to repair these unsightly holes? I have a mig welder and can hold my own using it but i'm worried about the welding thin thing GM sheet metal. Any other methods that don't involve welding that are still quality? I will weld if thats the best
. Just shoot some Ideas this way. Thanks.
