Adam, Realize that the "re-galvanizing" will be "cold" spray-on galvanic paint. You may wish to discuss this with your client. You can get galvanized couplings and I believe galvanized mech tees with factory applied zinc. Also, even with precautions the fabricators are put at a greater risk when welding on galvanized pipe. talk to your Victaulic rep about solutions before making a final decision.
