Heat shrink tubing- weather tight seal
I'm working on a engine harness and after much reading of debates between 'proper' crimping and soldering I decided to do a little of both throughout the harness. Some what of an test really to see how both hold up. Anyways after crimping some non insulated connectors to my wires, I was going to buy some adhesive lined heat shrink tubing but I have a ***** ton of plain heat shrink tubing laying around that I usually use for inside car wiring etc. Some of the wires I crimped will be under the hood so I want a nice water proof seal. I was wondering if there was a good glue that would not corrode or damage the crimped connector or wiring?
Basically is there an glue I can apply to the un-insulated butt connector and the small amount of exposed wire and then slip an regular heat shrink tube over it and shrink it, let the glue dry and be water tight just like adhesive lined heat shrink?
Some of these wires are for the ignition coils so using a glue that would interfere with conductivity would be my concern.
