Permalon beats the hell out of handling EDPM. I have a 300 gallon
EDPM (rubber) and 1000 gallon Permalon and the Permalon installation was
much easier. EPDM is about .040 thick and the Permalon is about .021
thick and stronger than the rubber. You do have to plan ahead because
Permalon is made to order then shipped, not cut from a roll.

Hal...great follow up...tell me more about permalon...I have never heard of
it!
