Remember the wax coating on electronics from the 50's & 60's?

[Mark42]

I' looking for something like that heavy wax coat that was applied to electronics from the 50's and 60's. It was thick, sticky, and completely coated everything except the tubes and their bases.

What was that stuff and where can I get it?

You may want a more modern conformal coating. Google it and find out the various types that fit your application and where to buy it.

I think the technical term for the stuff was "Cosmoline".

There's varnished cambric. It's still around if that's what you are looking for.


Enjoy

Simple shellac would work.

Depending on what you are coating....... have you tried the liquid electrical tape? You can use bees wax too which is pliable and sticky.... just keep in mind what you might have to go through to get the stuff off.

Bob_VT has a good point. I have talked to lots of boating people and others about liquid electrical tape and the consensus is that it is the stuff to use. I work in aviation electronics and this stuff works well to insulate electonic devices. You just have to take into account the amount of voltage and current you will be covering and what the proximity of it will be to other electronic or metal surfaces. The higher the temp and voltage the quicker it can breakdown resulting in a failure. Short circuits are a very bad thing in electronics.

I have liquid electrical tape. The problem I have with it is that it is too darn thin. Stuff is more like paint than a plastic coating. I use it, but its a pain in the butt to use laying on your back and trying to coat something over your face.... drip, drip, drip....

Need a thicker, stickier liquid electrical coating. Any suggestions?

We use this on printed circuit board systems and the item you are after is indeed called 'Conformal coating'.
Mrbigstuff is right on about it. Google it or try it under 'MG chemicals' (...just one of many brands out there). You can probably buy it or something similar locally. There are several grades (silicone, urethane, etc). A local electronics supply store would have it.
However don't spray 'connections' or you will lose your conductivity. You will probably have to mask those components.
Good luck.
