Most of the shops I called were not willing to try this with an exhaust, as they were afraid that it might float, warp, or even explode. Yesterday I finally had one shop on the phone who said that they were willing to try, but I have to go over there and show them the exhaust first. The main problem with this dipping process seems to be that the shape has to be such that the hot zinc can easily run in/out of the object and that is has to have holes to suspend it on wires. Well, I guess the VW exhaust has enough footholds where one can hook a wire, and when suspending it in a certain way all fluids should drain. I'll see if I can make this happen.
