Antifoul on Saildrive Leg? (Coppercoat)

sorry, I should have explained better.
What is the difference with it's make up as opposed to normal AF. I would have imagined the copper content would be higher yet it was said you can paint it onto aluminium leg which I would not do.

Yes the copper content of Coppercoat is quite high ... the website gives a figure.

Conventional A/F is a suspension of copper oxide in paint resin, either water soluble for eroding coatings or water resistant for hard. Coppercoat is copper particles in an epoxy resin. The copper content is similar for both, although it varies between cheap and expensive conventional paints. The reason that you can use it on aluminium is that the epoxy surrounds the copper particles, isolating them from each other. Thus there is no electrical continuity, so no galvanic corrosion.

As "Haydude" says. Absolutely not coppercoat. Make sure saildrive leg is properly primed prior to antifouling. Do not put propodrev or trilux onto bare metal.

I will shortly be taking delivery of a Volvo Penta D1-20 with 130 saildrive. Can I expect the leg to arrive primed?
