Alright got the first layer or bondo sanded down and added a second layer to fill in the hole more. Again I used 80 grit sand paper to smooth out the bondo.
Ok second batch of bondo dried, and I got it sanded down again with 80 grit, then when to 180 to make the transition between plastic and bondo. Finally I finished it with 320 to make it smooth.
Shot some primer on it and the line is looking really nice on the piece.
Finally which I'm still in the process of doing is shooting the black on it which is a semi gloss. I will be finishing it up once i get a couple coats of this down with a flat black to make it look OEM.
