At the convention, we ask Rick, who is a marine coatings expert, if he could put together a recommendation on a coating system for a typical steel hulled psub and he did. Attached is his recommendation. It is pretty much what Scott has done on Trustworthy. </div><div id="yui_3_16_0_1_1430485182297_10377" dir="ltr"><br></div><div id="yui_3_16_0_1_1430485182297_10367" dir="ltr">Jon, I am not sure this ever got posted to the PSub site but I think we should added under resources some where as this is an ongoing issue with anyone building as psub.</div><div id="yui_3_16_0_1_1430485182297_10368" dir="ltr"><br></div><div id="yui_3_16_0_1_1430485182297_10376" dir="ltr">Cliff</div><div id="yui_3_16_0_1_1430485182297_10214"><br><div id="yui_3_16_0_1_1430485182297_10213"><br></div></div><br> <div id="yui_3_16_0_1_1430485182297_10239" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div id="yui_3_16_0_1_1430485182297_10238" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_1_1430485182297_10237" dir="ltr"> <hr size="1" id="yui_3_16_0_1_1430485182297_10385"> <font id="yui_3_16_0_1_1430485182297_10240" face="Arial" size="2"> <b><span style="font-weight: bold;">From:</span></b> Alec Smyth via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, May 1, 2015 8:14 AM<br> <b id="yui_3_16_0_1_1430485182297_10371"><span id="yui_3_16_0_1_1430485182297_10370" style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] Zinc coating<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_1_1430485182297_10243"><br><div id="yiv4651471406"><div id="yui_3_16_0_1_1430485182297_10242"><div id="yui_3_16_0_1_1430485182297_10241" dir="ltr">Hi Brian,<div id="yui_3_16_0_1_1430485182297_10372"><br clear="none"></div><div id="yui_3_16_0_1_1430485182297_10244">There's lots of dirty, noisy, or smelly jobs building a sub, but sandblasting our little hulls - in particular the inside - has to be right at the top of the list. 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 id="yui_3_16_0_1_1430485182297_10245"><br clear="none"></div><div id="yui_3_16_0_1_1430485182297_10246">Best,</div><div id="yui_3_16_0_1_1430485182297_10247"><br clear="none">Alec</div></div><div class="yiv4651471406gmail_extra" id="yui_3_16_0_1_1430485182297_10248"><br clear="none"><div class="yiv4651471406gmail_quote" id="yui_3_16_0_1_1430485182297_10249">On Thu, Apr 30, 2015 at 9:25 PM, Brian Cox via Personal_Submersibles <span id="yui_3_16_0_1_1430485182297_10375" dir="ltr"><<a id="yui_3_16_0_1_1430485182297_10374" href="mailto:personal_submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>></span> wrote:<br clear="none"><blockquote class="yiv4651471406gmail_quote" id="yui_3_16_0_1_1430485182297_10252" 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 class="qtdSeparateBR"><br><br></div><div class="yiv4651471406yqt3368672402" id="yiv4651471406yqt04259"><div id="yui_3_16_0_1_1430485182297_10251" style="font-family: Arial, sans-serif; font-size: 10pt;"><div id="yui_3_16_0_1_1430485182297_10250">All,</div><div id="yui_3_16_0_1_1430485182297_10253"> </div><div id="yui_3_16_0_1_1430485182297_10254">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 class="yiv4651471406HOEnZb"><font color="#888888"></font></span><div id="yui_3_16_0_1_1430485182297_10255"> </div><div id="yui_3_16_0_1_1430485182297_10256">Brian</div></div></div>
