...unless its aluminum, then just ball up some tinfoil and mash it in the hole....

p.s. I know I can be a real smart @ss!! Believe me, my wife lets me know all the time!

But seriously, if it is aluminum, I've seen people repair aluminum with a special aluminum welding rod and a torch, although I wouldn't know where to find one without going online.

Let us know what you do.
