removable potting compound ?

Have you tried rubber cement?

No, but that's and idea I hadn't even considered. Might be more what I'm =
looking for. Something that can be peeled off later sounds like the =
ticket!

Is there such a thing as a removable potting compound of the type used in
electronics?

I'm looking for something to secure wires and/or screw settings against
vibration and strain but that can be removed for resoldering & adjusting.
Maybe just plain silicone sealant is the best bet, but in the past when I
have tried using it in thickness greater than 1/8" or so it either did not
cure or took forever to do so! I want something I can apply once and cure in
24-48 hours at the most. I want to be able to remove it later without
destroying the product it is used on ( most likely a circuit board of some
type; DC-DC converter with screw terminals, etc.  ... )

Thanks !

There is a two-part Room Temp. Vulcanizing Silicone putty than will cure in
about a half hour. Nothing will stick to it so you will have to devise
mechanical methods. My supplier has disappeared but I'd try McMaster Carr
first.

Hot Glue?

    There's Fine-L-Kote, which is a conformal coat that's sprayed on,
and there's Fine-L-Kote remover.  But that's a conformal coat, not a
potting compound.  It's also a moderately hazardous material; you
need ventilation, a respirator, and a fire extinguisher.

    Search for "conformal coating", not "potting", and you'll find
what you're looking for.  "Potting" is where you fill a container
with some hardening material.  Read this:

    What problem are you trying to solve?  If it's loose screws on
screw terminals, the answer is deformable phosphor-bronze lockwashers,
which is what the military uses.

Excellent info on that page. But you almost need 3-D glasses to read it! =
From that page I found the Loctite link, (http://www.loctite.us )  I had =
no idea they make so much more stuff than you see on the retail shelves!

Anyway, thanks for the suggestions on what to search for. That should be =
a big help.

You might try hot glue. It might come lose from slick surfaces,
but it is fairly easy to remove when needed.

In the past at work I used Dow Corning 182 or 184, it's a clear silicone
coating that can be pealed/scraped away when needed.

Yeah - I think that's what I going to try to use.
Thanks !

Just make sure you clean ALL of the solder flux off of your PCB.  The
silicon conformal coating does not like to stick to solder flux!!!
