Hey everyone, I would like to fill in some small holes in a fender. these holes are from some of the emblems and are about 1/8th inch(?). Is it better to use a filler or maybe use a copper backing and then use a welder to gradually fill it then smooth it out?
thanks guys.

Use the cooper back up method and weld them. Will last forever as compared to bondo.

my mig will fill holes about a half inch without even using a copper backing. definitely weld it though.
