Years ago I bought myself a sand blaster with the intention of doing this job myself. Very bad idea. It was a complete pain, especially recovering the sand to pass it back through, which required one to pass it through a sieve to remove any kind of foreign particles that would clog the nozzle. I had clogs pretty much all the time, sand everywhere, and ended up taking the sub off to have someone with proper facilities deal with it. I generally tight-fisted, but sand blasting is THE job I don't mind outsourcing.</div><div><br></div><div>Best,</div><div><br>Alec</div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Thu, Apr 30, 2015 at 9:25 PM, Brian Cox via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid"><div><div class="h5"><div style="font-family:Arial,sans-serif;font-size:10pt"><div>All,</div><div> </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><span><font color="#888888"><div> </div><div>Brian</div></font></span></div>
