This Plastic Repair stuff should work like a charm.

Started by wrapping a small piece of plywood with aluminum foil.
and taping it to the back of the bezel.





Then glob on the plastic repair resin in a nice thick even coat
around the edge.




About 5-10mins later you can start you can start molding a little
by finger tip take out some of the bigger high spots. and after about
15mins you can remove the wood and carefully peal off the foil.







With in 1-2 hours its hard enough to cut with a drimel and start making
rough cut. Stuff sets up as hard and strong as plastic in about an 1hr.





Repeat, sand, shape, repeat, sand shape ...... you get the point.
Will post up some completion pictures in a couple of days.
