Thanks Roberta, I've done enough cars with grills to start at the weakest and cut to the strongest point. On the side louvers and front grill, I started at the bottom and moved up replacing the cut outs as I go (and I go slow) 0/3 superior puzzle blade, then blue tape everything back in place to give it strength for sanding the back. I kind of enjoy it but I had one break out on the second grill from the bottom in the front. The BBPW had a void and broke out. I was able to salvage the piece and CA glue it back in place. Yikes!
