I had a lot of trouble getting the medium tack to stick to some of the stuff I was testing at first…it wafted up and caught fire in one episode that I wrote up once…somewhere. Fireflies
Now that was after brayering the masking down, (but not enough apparently), and I let it sit in a fairly humid room while I went to have dinner. Not good. The strands lifted, caught fire and wound up in the exhaust fan…which led to the write-up on how to clean your fan.
