Avoid galvanic corrosion: Which FG to use before CF?

[system]

Hey guys. Curious on which fabric of fiberglass you would recommend to overlay aluminum trim so the top layer (carbon fiber) does not cause galvanic corrosion? I would think the lightest possible, but not sure.

Unless it is possible to lay the CF on top of aluminim in such a way that will not lead to corrosion??
-Resin first, then CF on top of resin barrier?

I appreciate your feedback.

Anodize to MIL-A-8625F Type IIB and your good to go

I wonder if some ethicing primer paint would do the trick or not? Maybe do a test panel and place it in the extreme heat or wet area and see what happens?

Any fabric. If it is a thin one, add 2 layers. Make SURE you let them gel well, or cure with peelply on top so you can finish bonding the CF on the Al/FB part.
