Does anyone know what type of plastic the dash hull is made of. I am looking to try to anneal and old one to see if it can be softened up so not to be brittle. Two methods to try would be a oven with heating elements and a tank large enough to boil it in water, with water heater elements. The idea is to bring the part up to @ half the melting point of the plastic. This would anneal the plastic. It's a common practice with plastic parts after molding. It relieves stresses in the parts. So that's the reason for the question.
Any thoughts about this welcome.
