aluminum reservoir

[Delorean17@xxxx]

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
