HI, My car had an aluminum coolant reservoir on it when I purchased it(Delorean ONE part I believe) but it leaks a little bit where the copper neck is soldered to the tank. I removed all of the remaining solder and rebrushed the entire tank last night. I took it to 3 shops today to have the neck reinstalled and they said there is no good way to weld or solder brass to aluminum and that I should just use Fas-weld steel epoxy to put it back on. Any other ideas before I epoxy the neck back on? I can't weld or solder! Thanks David
