Im about to paint my car and i gutted the whole car completely. There are some dime/nickel size holes in my interior that i want filled. Whats best way in filling those? Thanks!

 

I would cut a piece of sheet metal (aluminium/ss steel) that is slightly bigger than hole, shape it to sit flush with the surface surrounding the hole and then epoxy it on. Make sure the surfaces are clean before using the epoxy. I used a jewlers epoxy used with faciting stones and such.

I used this method to patch my radio antenna hole before filling it flush with the surface.

 

bullet holes?

yeah i would say about the same thing, hell, if you wanted to, go ahead and use a nickel or dime, whatever lol
