Liquid Insulating Tape

Now available in a spray can:

ebay link

Not cheap but I've ordered a can out of curiosity. Could be handy if it works, the brush on stuff made more mess than Sika

This stuff works pretty well. I used it on my trailer lighting and it solved my continuing lighting headaches. Originally connections were just crimped and salt water would enter at the crimp, cause electrolysis there and corrode the rest of the wire under the insulation as well.

I solved this problem with marine grade connectors that had heat shrink exterior insulation and the liquid electrical tape (the stuff I used came in a can with a brush in the cap, but it was the same brand). When prepping the wire for crimping, after stripping the insulation I would paint some of the liquid tape adjacent to the stripped wire. After crimping I heat shrinked (shrunked?) the connector's insulation and could see the liquid tape completely fill the space between the insulation layers. I would usually dab on some more for good measure. I have not had a problem with the lights since I rewired the trailer this way. The trailer is totally submerged in salt water ever launch.

If you use the adhesive lined shrink tubing/connectors, you lose the whole brush-on-the-sealant step. You can also walk easier due to your wallet being so much lighter.

I've also had success by using hot-melt glue stick slivers and regular shrink tubin/connectors (when I ran out of the adhesive lined.) Shave off a piece of glue stick and tuck it into the sleeve just before shrinking.

I use adhesive lined tubing as well - good stuff.
An example of where the spray could be handy - the back of a switch panel with all those spade connections and soldered connections etc. It'd be nice, once installed and wired, to just put a coat over the whole lot to keep the moisture out.

liquid electrical tape, have a boat use it

I've put a lot of wire in boats over the years (who hasn't) and it goes like this: solder, flop on plenty of liquid electrical.tape, slide your heat shrink tubing over that and proceed to shrink. The excess liquid will ooze out and you will have an excellent waterproof connection. Takes a little extra time but well worth it. Amazing how little a exposure of copper in a marine environment brings on the green slime... I like Martini's idea of using the spray on panels, exposed areas, etc. Great stuff.
