Was thinking of hanging up my original plastics since they are mint and would be quite a shame if I dropped it. There are so many aftermarket "plastic" sets out there in both ABS and Fiberglass. I heard some one say here that some plastics MELT! I looked up the melting point of ABS=220F which is the temp of our cooling system and I IR'ed my pipes and see temps at 350f to 400F. Was wondering if anyone has any experience with the aftermarket stuff out there. I have seen some guys selling Fiberglass which has better ability to resist the heat.
