From what I can tell there are two options for antifoul paint on the outdrive:
1) Quick spray on type. Just clean the leg, rough up the original paint a bit, and apply.
2) Interlock. Clean the leg, sand the old paint off down the aluminum, apply primer really really well, and apply interlock coats.
The cons that I've heard about the quick spray on type is that it flakes off and doesn't do nearly as good of a job. But, I'm a little hesitant about about applying the interlock (contains copper) and trusting that the primer will do its job to keep the two metals from reacting. What happens if it gets a chip in it exposing the aluminum?
This is a moored boat and already has Interlock on the fibreglass hull. She doesn't get out of the water much and needs something to keep her clean(er).
Thoughts? Experiences?
