Dissimilar metals are enemies forever (even similar metals do not like each other) Paints and other covers are very difficult to cover aluminum. I suggest, unless you absolutely have to do not do it.
I have an aluminum sailing vessel (Trintella49A).
All possible means and methods were taken to place a barrier between the Alu structure and components.
The Generators sit atop of Wood. The wooden platform connectors have no direct connection with the Generator and Ships Frame.
Another major concern must be the electrical connections / Grounding (Floating) from the generators to the rest of the electrical and electronic systems. Be very careful.
Happy to give you some of my insight.
