I did it this week use the stencil that comes with it to line it up. I used sticky takt to hold it on without damaging the paint, it came out well. I covered the holes perfectly. I filled the holes with a resin before adding the new badge..I don’t have any original badging on mine in or out. You shouldn’t have any problem doing it yourself, unless of course you’re like one of those cement handed wingers that couldn’t hit the broadside of a barn from the slot.
