I use sign makers plastic for making the mold flanges. It's cheap, cuts nicely and shapes with very little heat, and easy to get.

Masking tape so the hot glue doesn't permanently stick to anything.
Use a lot of cripples so the plastic doesn't move or break off during laminating, last thing you need with wet 'glass!


I welded in a fairly stout inner structure while the valence was still on the car. Given the weak-@ss nature of how the shape of the spoiler was created, can't have anything flexing once it comes off the car.




Other side of the bumper mold laminated.
