Electrical insulation in a squeeze tube?

[Decline58]

I am rebuilding a 1950's vintage Mall Electric Chainsaw. In the electrical motor where the brush wires make tight turns, some of the insulation has cracked off the wires. I am looking for some electrical insulation that I can goop on to these wires to prevent shorts. I see that there are some specific products made for this, but I am wondering if you all have used any "consumer" products for this purpose, bathroom caulk, liquid nails etc.

Since I will be using a very small amount of the goop, I would like to choose a product that I will be able to use elsewhere also.

Thanks in advance for your help.

You can get liquid electrical tape for $6-7, it lasts for a good while and can come in handy for anything in the future. Unless you have another immediate use for the rest of a tube of caulk or liquid nails, it is going to go bad. A quick google search suggests that any acid cure silicone (that smells like vinegar as it sets) would not be good for an electrical application.

I suppose you could always hot snot it (hot glue gun).

Heat-shrink tubing over the existing (but cracking) insulation?

Liquid electrical tape is what you want. I've used it many times and found the Gardner-Bender brand to be the best:

It should be available at most hardware stores.
Be sure to do it in two stages in order to get maximum thickness out of it. Coat the wires even where they aren't cracked, in order to help prevent future cracking.

Garagelogician and others,
Thanks for the help.
I'm trying to post pics, but I haven't figured out how to post pics, but I will (I'm a newbie here).
It is interesting that you found that info via Google. I had a suspicion that silicone compounds were the answer, but I tried googling it, no luck, I even called 3M and DAP with no luck.
Anyway, I was able to get a small portion of vinyl tape around most of the exposed wires and then gooped around with GE silicone sealer. I should get it running this weekend, I'll let you know how it worked.
Thanks again for the help.

Use Pratley quickset epoxy clear glue or equivalent.
