fiberglass for hole, will it work Options

[cyb593]

will it work just as well as metal being welded back in this tiny holes. i am getting everyone saying that bondo will eventually break loose after a while thats why u have to have little pieces of metal welded back in there. could i not weld and put fiberglass in there instead and it hold forever and on or will it be like the bondo and fall out eventually and how eventually??? just curious i am having issues with my wing as u can see it is costing me more money than i would like to spend on a damn piece of fiberglass. anyways any help would be appreciated. thanks

Your best bet is to get the holes welded from the inside, then use a very thin coat of good body filler(not Bondo...something like Rage Gold works very well.)

You may be able to get away with fiberglass though. Fiberglass does bond to metal very well actually. The problem is that when it is subjected to heat, fiberglass and metal don't expand at the same rates at the same temperatures, so the bond can break and crack.

I patched a couple holes with fiberglass on my brother's car, and they've held up fine for over a year. But the best way would be to have metal welded.

Whatever you choose to do, don't just fill the holes with body filler.
