[PSUBS-MAILIST] Zinc coating

[swaters@waters-ks.com via Personal_Submersibles]

Not sure about yhe zinc coating. I used Macropoxy as the first coat and High solid poly as my second coat. I don't know if that helps, but it is what I did.
Thanks,

All,
 
Ok, I was going to take my pressure hull ( it's finished , BTW) down and have an outfit zinc coat it but now I'm thinking that I should spend that money on a heavy duty air compressor and a sand blaster and do it myself.  Since I'm sure I will need to be recoating places where I'm doing thru hulls and such.  But my question is do I need to worry about the compatibility between the zinc coating and the epoxy that will on over the zinc ??   Should I put the zinc on the inside too ?   Are there different types of zinc coatings?  
 
Brian
