This little curb side find was missing some of the decorative overlays and details on one of the doors.
To recreate those details I used the following steps:
First I cleaned the entire radio cabinet and removed the doors. I’m using the good door to make the mold for the missing cross/fleur piece.
Lightly coat the piece you’re molding using a cotton ball and WD40.
Make sure you’re covering the detail or trim entirely and that you’re using a thick layer of glue or silicone. If you make the mold too thin it will tear when you go to release it.
Once your glue or silicone has setup. Carefully remove your new mold. Lightly coat the inside of the mold with cooking spray or WD40 and fill with Bondo Body Filler (this is a 2 part mix sold as automotive body filler). Let the Bondo setup until hard, about 20 minutes is good.
Once the Bondo has setup, carefully remove your new trim or overlay piece. Depending on the thickness and size of the piece you may have to trim off the excess Bondo. This piece I was replicating was very thin and with such a shallow mold I was bound to have to do some trim work.
Take a sharp razor knife and carefully trim your excess off. Then by hand, lightly sand your edges smooth with high grit wet/dry sand paper.
Lightly sand the surface smooth by hand.
