[V8Vairs] What's being used for cooling system pipes?

[Dewey Thomas]

Trent : Thanks for the refresher electrolysis course. I wasn't trying to be 
facetious in the response--just responding to his original request, I have 
used exhaust tubing-non coated varieties- in radiator systems ,with no 
problems; if you can accept 30,or so, years of service;without replacement. 
I am quite familiar with aluminized and galv. steels ;and the reason for the 
coatings---I didn't say it would stop rust/corrosion; but "retard"---.No 
response is invalid;we're only voicing an opinion based on individual 
experience and the objective as to what we think the requester 
wants.Unfortunately;quite often, the response can be at opposite 
ends---(grin). Probably ,my next application will be with either Sched 20 or 
40; I find it's much easier to glue than weld---.
I lean toward 20,in that the press. is only about 16 psi and temps to about 
the 200-220 F  range. Dewey
