I think it was Mike G. that recommended MAPP gas for heat-shrink on the Ace connector. That stuff is way too hot and catches lawns on fire. I tried backing off from the direct flame to keep the tube from getting burnt, but that only increases the area exposed to the heat up to the insulation, and still burns everything. I was in pinestraw, and to avoid a forest fire, I hung the connections up in the air while heating them. It was at that moment I felt like I was toasting marshmallows. You know how some people let their marshmallows catch on fire and then say they like them that way? Then I remembered the Pete story about the marshmallows. Anyways, I'm keeping the MAPP gas in the garage for getting seized nuts off of stuff. I have a heat gun, which is perfect temp. for heat-shrink, but I wanted something faster to set up and portable.
