This kind of stuff worked for me in 16. A thin coat around the edges. It ruins their car or bike, their clothes, their door knob, it even ruins their keyboard when they post what in the hell is this stuff to DU.
Some is colored, go for the clear stuff. Imagine them getting it in their hair. This stuff is insidious. It is a glorious punishment. Close your door... sticky hands. Drive your car, sticky hands. Regular detergent wont remove it from clothes. Sand it off of your hands and touch any of the above, sticky hands.
As Q says, these people are dumb.
When they started stealing my T&P signs I went all chemist on them. What if they steal your sign and cant remove it or it’s effects?

Plus it is safe. Let them bitch all they want. You are just using Trump signs as fly paper.
The technical aspect of shenanigans is what I apprediate the most.
