Don't know the answer to this one. The sandblaster I talked to
swore a zinc thermal spraying protects steel better than anything
else because it acts as a sacrificial anode. But from what I can
find out from other sources the zinc coating still needs to be
covered by paint because sometimes it does not adhere permanently
and it can chip. So I have the option to have the hull zinc
galvanized by thermal spraying but I don't know if it's worth the
money.<br clear="none">

The sandblaster/painter I talked to said the coating goes on one
side only, presumably the outside because it would be way too
difficult to get the thermal sprayer into a small sub to
effectively coat the inside.<br clear="none">

<div>All,</div>

<div>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? </div>
