Step 4 (optional):
As you can see from the pic once you cut off the badge it leaves a hole on the top of the grill but not the bottom. Once you have it on your car you won't see the hole but I like to play with fiberglass so I filled it in. Once the glass dried I used bondo to smooth it out and fill in the rock chips that were there from driving. Here is the pic filled, sanded with the 80, then 150 grit paper and ready for primer.
