Then you need to really consider the surface prep of the Al use acetone and thurly scratch the surface to promote bonding. Here is a nice website and you just select the substrates and it gives you the adhesive recommended for the job. The Crestabond® series adhesives is what they are suggesting.

Thick the resin with silica so that it´ll keep in place better than clear resin. Remind surface preparation on both Al and Carbon.
