Looking for a pint of either molybdenum or tungsten disulfide oven cure coatings. Years back the moly was easy to get... 200-300 now it's like 800-1200 and 2500 for tungsten. What happened?

Really hoping some machinist engineers may be able to point me in the right direction.

Only thing I'm finding is gunkote Fire arm coatings online.... They work but not as good as other products I used many years ago.
