It's been suggested that one first coats the aluminum with the epoxy. Then,
while it's still liquid, scrub the aluminum with a wire brush to cut thru
the oxidation and permit a bond to the real aluminum.

There was a discussion in this newsgroup recently about gluing broken
aluminum with epoxy. It seems instantaneous oxidation of exposed aluminum
prevents a good bond with epoxy.

I have an aluminum casting which has broken. Does anyone have any
experiences or recommendations on the likelyhood of success, glueing
it back together with epoxy? I have West System on hand, and can
fairly easily get other products (e.g. Aluminax). Any tips,
techniques, or pitfalls I should be aware of?

thanks,

John
