Good eye
Yep, I drilled the panels out and then sanded with 80 grit to give a good bonding surface for the material to adhere (lessons learned from previous builds) to and then aimed and secured the mounting baffle with hot glue and pieces of 3/8" wooden dowel rod. Using thick rod like this certainly helps with stability for the piece. Once I get them hot glued in place, I hit the dowels and the surface with resin to soak them and bond them to the piece. Then, I started in with the chopped matt and resin, followed with Rage Gold filler. And lots of sanding....
