Zinc coating and two pack epoxy worth the price?

This confirms the statement made here

 

"...

If the Zinga layer is sufficiently damaged to expose the base metal below, the steel would form a layer of surface rust but no corrosion would take place beneath it. In other words if the surface discolouration was removed the steel below would not be pitted or eroded. This is called "throw" and enables Zinga to protect bare metal up to 3 - 5mm or so away from where the coating ends...."

And it's true as I can confirm from experience, best thing I did to my boat

Are you allowed to paint the hull in marine antifouling?.....not TBT ,obviously ,but a copper one?

Be very careful of using the copper based anti fouling on either an aluminium hull or a steel hull without there being a full sealing epoxy coat under it, or corrosion/pitting will take place between dissimilar metals.

Thats a good point.....however my interest in the antifouling was recovery of 30kg of copper per drum.
