welding (with a mig) worked great for me, but my 55 is like a tank. just pulled the trigger for a half second and let off.several times (then grind down) i really dont know about this on the thinner sheet metal you have... bondo would work as long as it goes all the way through the hole so it wont fall out. forget spot putty, it wont work. dont get the area too hot or it will warp if it doesnt burn a hole
oh yeah, if you use bondo always get the "all-metal" kind, and never leave bare metal exposed. primer immediately even if you are sanding it off at a later date. that way it wont rust.
