I am a boat and airplane (composites) guy so am familiar with epoxies - I know Devcon.

I thought it would have to be a filled material, kind a like JB Weld (which is nothing more than 30 min epoxy with aluminum filler - but a good epoxy)

I understand the surface prep and the problems of adhesion, just looking for as many tips as I can.

I can see going with as long a cure time as possible (typically means better strength and adhesion) and then also filling with aluminum powder so the two items as as close as possible to each other?

A picture of your piece would be helpful. Is it a section that flaked off or just a piece of epoxy. It will help me to understand what I am looking at

Thanks
