Doesn't TP Tools suggest black pipe anyway? Their system design looks like
it minimizes moisture vapor in the piping so if you build with the drains
they suggest it shouldn't be a problem. You could use the Garage-Pak system
(www.garage-pak.com) that's used/advertised on the car shows on Speed and
Spike, but I'll bet it's quite pricy compared to black or galvanized pipe.
Can't hurt to check.
FWIW,
