Plugging emblem holes in fenders

The backing plate makes it pretty simple. Your not going to fill it in one shot. It'll take a few zaps, and let it cool between. If I have access I prefer to weld on the backside. There should be very little grinding on the face of the fender. In fact you may be low, but you're skim coat will fill it in. Pretty simple really. Anything specific you were wondering about, or concerned with?
