Model Railroading > Insulating paint

I'm doing some repairs on an 89 ft flatcar that I put a FRED on at least a decade ago. All the electronics are contained in the frame, but the leads to the LED are exposed where they come up onto the coupler. (The coupler is a plastic Kadee.) When I first did this conversion many years ago I painted the leads with a black insulating paint. They need to be recoated, but I don't recall what I used for that before other than it was in a relatively small jar. Does anyone have suggestions for a brush-on insulating paint in black?

Dano:

Visit your local hardware store and look for Liquid Electrical Tape. It's a viscous liquid, available in several colors, more or less a liquid form of plastic insulation on wire, that can be brushed on a desired surface. Works great, and dries really tough.

+1 for liquid electrical tape. Big box stores also carry it and online stores.

One jar ought to do about 12,000 FREDs.
I use it often but it only lasts about 2-3 years after opening.
I've never worked down to the bottom of the jar, but I never want to be without it.

Hmm solution possibly for my MM( ON30 engines needs something just hoping I can find the shorts. Yes I turn the lights off and have found some but not all.
 

Spray or dip: Plasti-Dip Spray or Rust-Oleum dip. Most often used to coat tool handles with an insulating better grip.

I think most of the products mentioned are quite viscous, and probably tough to manage on small things.  Maybe low viscosity varnish would be easier to control.

This sounds like the stuff that's on magnet wire.

Thank you to everyone who replied. I will give the liquid electrical tape a try.

sf1010 noted "I think most of the products mentioned are quite viscous, and probably tough to manage on small things."

I am somewhat concerned about this, but I'll play with it and see. The original product was something from one of the model paint manufacturer's line and came in a small bottle like hobby paint. I remember when we used to do more modeling and had more of these products available. [sigh]

Probably similar.  Magnet wire is often referred to having "enamel" insulation.
