Fish Paper

I use thick card stock and it works well. I actually have used butter boxes as source material, and it works great. I've had pieces in place for years and years without issue.

I've found that just about any thinner type cardboard works.  I've used the cardboard backing from tablets; I've used matchboxes that I scrounged up; I've used whatever is handy.  Too thick and I find it too hard to shape. They all worked well.

Since the cardboard isn't disturbed once it's in place I'm guessing that's why it's held up so well for me for 20 some years - and I set up and tore down my Christmas layout each year.

Anybody found an excellent substitute?

When I wanted to make an insulated rail, or repair bad track insulation, I used friction tape (cloth electric tape).

Yes sir black friction tape or as we called it as kids "tar tape" is the only thing I've ever used.

Some of the credit card applications, or the ads for Internet and telephone service that come in the mail are printed on heavyweight, plasticized paper. That would work once it was painted black.

Fish paper is still the best, though. Insulating electrical things is what it was designed for.
