Insulator in paste form

Is there an insulator of choice in paste form where I can use to cover
some of the wires that get exposed in small electronics projects?
Using tape sometimes doesn't work because it's hard to reach the area.
I tried to use glue but it gets all messy. Is it epoxy?

Thank you.

** Try using a * silicone sealant * , be careful to chose the kind sold for
use with metals.

" Silastic" is one brand, there are many others.

Silicone has excellent insulation quality and dries fairly quick.

Do not use sealants that smell like acetic acid !!

Most epoxy formulas are excellent insulators, so might serve
for this function. The quick cure kind (50:50 mix that
hardens in a few minutes) is soft and can be dug off, if you
have to repair something. Viscous liquid versions are most
common, but can be thickened up to reduce dripping, by
stirring a little talcum powder into each of the parts of
the mix before combining them. If you mix first, then
thicken, you risk having the whole thing set up before it is
placed. The cure time can be extended by keeping the epoxy
cool (mix on a file card laying on an aluminum pan you pull
out of the refrigerator, just before mixing).

I keep this handy for many uses:

Silicone sealant works well.

Silicone is not "erosive" you fucking retard. Try looking up those
big words that you don't understand before using them.

You moron, it's fools like you that make the world go around jack ass.

Oh yeah, I forgot. You're just an insignificant little twit/twat. What
ever fits you the best. Most likely both in your case.

I guess it's time to shove this idiot down the stairs again.

The word is 'Corrosive', moron. Sorry, I see that you prefer to be
called a retard.

It states right on the tube not to use acetic acid cured Silicone
caulk because it is corrosive.

Exposed wire in itself is not a bad thing. Only if there's a risk of
something else coming into contact with it (and why are there any loose
and uninsulated wires that will?) does everything have to be insulated.
Well, high enough voltage you should be careful with.

It almost sounds like you might be talking about wires at the bottom of
a circuit board or perfboard. If that's it, the wires aren't generally
exposed since they are on the underside and presumably facing some surface
of the box it's in. If the box is metal, the trick is to put a sheet of
some insulation between the board and the box, just in case. Commercially,
you see quite thin pieces of plastic or mylar there, any plastic you
can get your hands on would work. Not even needed if the box is plastic.

Other tricks are covering the exposed wires with tubing. You get
flexible plastic tubing of the right size, slip some on the wire, then do the
soldering. Then you can pull the tubing over the exposed connection. Some
times you can even make do with insulation pulled off a bigger diameter
wire, instead of buying the empty tubing.

Sometimes that's not suitable, because the connection is too big so
a large enough diameter tubing won't hold. So you buy some heat shrinkable
tubing, and as with the plastic tubing, slip a short length over the wire
before you solder it. Then bring it over the connection, apply some heat,
and the tubing shrinks. You get a nicely insulated connection.

If it's to tack down wires, either dab on a bit of hot-melt glue,
or use wire ties.

To protect junctions, simple vinyl tape is not the end of the list;
heat
shrink tubing, and fusion tape (rubbery stuff that forms a solid
blob),
and liquid tape are all useful to cover bits that could be an
embarrassment if they made contact with people or metal.

To protect a long wire run, there are sheathing materials, including
'spaghetti' tubing, but usually you will want to buy sheathed
cable instead of building your own.

If you want to protect a complete circuit, of course, you want a
box.
Bulkhead connectors and grommets... all good for protecting wire.
