They should be prepping the joints just prior to welding so that's shouldn't be an issue, plus the heat is going to discolor and/or burn any surrounding paint. When you get it back, sandblast and prime the whole thing.</span></div><div id="yui_3_16_0_ym19_1_1534254315208_26258" dir="ltr"><span><br></span></div><div id="yui_3_16_0_ym19_1_1534254315208_26258" dir="ltr"><span id="yui_3_16_0_ym19_1_1534254315208_26372">However...given the difficulty of both prepping and painting the interior, I think I would take the opportunity to get as much of that done first, as possible. You can touch up afterwards any burn marks from welding but at least the bulk of it would be finished.</span></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1534254315208_26301"><br></div><div class="qtdSeparateBR" id="yui_3_16_0_ym19_1_1534254315208_26301">Jon<br><br></div><div class="yahoo_quoted" id="yui_3_16_0_ym19_1_1534254315208_26390" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1534254315208_26389"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_ym19_1_1534254315208_26388"> <div dir="ltr" id="yui_3_16_0_ym19_1_1534254315208_26387"> <font size="2" face="Arial" id="yui_3_16_0_ym19_1_1534254315208_26391"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> David Colombo 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> Tuesday, August 14, 2018 1:21 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> [PSUBS-MAILIST] Sand Blasting<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_ym19_1_1534254315208_26392"><br><div id="yiv7570110300"><div dir="ltr" id="yui_3_16_0_ym19_1_1534254315208_26394">
<div id="yui_3_16_0_ym19_1_1534254315208_26393">Hi Guys, I have a question on sandblasting my hull parts. The
initial fabrication is almost complete and I was thinking that I might
want to have the parts sand blasted prior to welding them all together.
Maybe even a light primer seal coat to slow flash rust as it may be at
the welders for a couple of weeks. Any thoughts or advice would be
appreciated. I know right now every time I get near the parts I'm
covered in black smudges.</div><div><br></div>
