I have some electrical connections I'd like to temporarily protect. They are about 14ga wire, soldered to large pads on a PCB. Obviously shrink tube or electrical tape won't really work. I could use some liquid electrical tape, or silicone, or epoxy but those are too permanent, will be a pain to get off if/when I need to desolder, and resolder the connection.
I'm wondering if there is anything out there, that works well and has been proven, that sort of has a consistency similar to silly putty (but a little thicker, and less prone to sagging). Something that can be smeared/pressed around the connection, and will adhere and stay put well, but when it is time to remove, it can pull right off with zero residue.
Does such a solution exist. Or is there a better solution I'm not thinking of?
Clean your PCB well after building it.
Then apply some hot glue (you know those sticks you put in a gun like applicator which heat it and make it fluid).
You can mold the glue to some extend after applying it, and removing it won't be too difficult.
If you do not clean the pcb, the glue might not stick.
And i don't know how well it does its insulating job.

If it comes right off, will it provide any physical protection? You might try using the rubbery liquid paper/poster glue that comes in a jar for the coating. This type of glue can usually be rubbed off of what it is applied to.
I read on a forum a while back (no clue if it was this forum or another). That you can make your own Sugru like compound with silicone caulk and I want to say baking soda. Look around for it, as they exact ingredients and ratios were important.
That said, I would try to find the stuff from 3M. Pretty much everything they make is amazing, so its hard to go wrong there. (Said by an electrical tape snob that thinks anything less than Scotch 35 is worthless)
