This is all helpful, my concern is what I have witnessed over many years as the heat and fuel ruined the 5 min epoxy. Since it is electric, fuel is not an issue but there is plenty of concern about heat. I don’t know the deformation temp of the epoxy nor the exposure to normal environment so that is why I was asking. I am going with the 5 min and doing a thin coating of laminating to have a seal and redundancy. Sunlight will eventually ruin the epoxies but since it is inside the fuse, that is not an issue. <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'>Thanks<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'>Mike <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p></div><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><div><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'>From:</span></b><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'> <a href="mailto:nsrca-discussion-bounces@lists.nsrca.org"><u><span style='color:blue'>nsrca-discussion-bounces@lists.nsrca.org</span></u></a> [<a href="mailto:nsrca-discussion-bounces@lists.nsrca.org?"><u><span style='color:blue'>mailto:nsrca-discussion-bounces@lists.nsrca.org</span></u></a>] <b>On Behalf Of </b>Ted Sander<br><b>Sent:</b> Tuesday, September 13, 2011 6:54 AM<br><b>To:</b> 'General pattern discussion'<br><b>Subject:</b> Re: [NSRCA-discussion] 5 min expoxy<o:p></o:p></span></p></div></div></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'>I tend to use whatever the local shop carries – but do lean toward Z-poxy.
