Im going to start shaving my emblems soon, but i dont know how to cover the holes that are left..what are some ways to cover those holes cleanly??

 

Back them up with fiberglass sheets. Then fill with Bondo and smoothen out.

 

you can also weld them up but not to fast because if you go to fast it will make your panel worp and then put some metal filler on after you grind the welds down
make sure you protect the welds in the back becasue they will start to rust on you
