It's OK if you layer it on thick. It is runny so you can't expect it to stick like paint would.

I used to cover a threaded rod that was mounted to support a printer. But I banged my hand into it's sharp threads many times. This stuff was layered on thick over the two thread rods and my hands no longer got cut when I bumped into these supports. I also used it on the outside of a clothes washer drain hose that was leaking (applied when dry). It stopped the hose from leaking waste water onto my floor. I tried to use it to dip and coat tool handles to make grips more comfortable. But that failed badly. Couldn't get it to stick to the shiny metal handle surfaces. It does go on kind of runny and needs to be put on items thickly to seal them. That was sometimes a challenge. Is very messy and pretty much ruins any cloth you get it on. So wear old throw away clothes when applying. I also found that if I 3D printed some of my parts or figurines with a coarse or scratched up surface this would cover and stick to them as an outer coating. It wouldn't do to use it with anything with features as it would cover them up. But I was able to coat a few figurines with it and it gave them a very cool rubbery feel. I might order more but not sure when I will need it next.
