Any insight on the plastic coated aluminum used in the rapidair systems as far as reliability? Copper is probably the most commercially used, but it is quite a bit more expensive than the rapidair system. And for my home shop, I don’t think it’ll see the same stress as a commercial shop
Can't comment on the Rapidair system as I have no personal experience. I know it is quite popular around here. I'd have to count but in our car club I know at least three members have the Rapidair system in their shops and I've heard no complaints about it.
