teflon plumber's tape. About a buck at your big box hardware store, a roll will last years a couple inches at a time, a few range dates a month maybe. Works great.

I hunt with a smoke pole, so naturally I end up using T/C anti seize. You can buy it at walmart, its clear and petro-jelly consistency. the downside to anti seize is it likes to collect dirt, sand, crud so don’t use very much, and make sure you put a thread protector on your rifle, put the can in a pouch when not in use.
I use nickel anti-sieze because the copper can cause corrosion in aluminum and some of the suppressors have aluminum in them. Copper will work as well and the suppressor may not last long enough to worry about corrosion...
After cutting off and boring out a couple of stuck suppressors from customer guns I recommend the use of an anti-sieze of some sort. With all the carbon and buildup we get on suppressor threads it is possible to gall or pickup a thread and have a stuck can or damaged threads. If you're worried about dirt and crap collecting on the threads use a thread protector on the rifle and a plastic plug in the can at both ends.
