Not on my bike but I used it on the grill of my trucks and my rims as well.
Honestly I adore the stuff. It has been strong as hell and looks great. Just make sure to follow the directions and use lots of thin coats...not a few heavy ones.
ya i used it on my forks and turn sigs. its a quick way to get black. but if u want a glosses look to it spray some clear over it. its not a pro paint job but it looks ok. ive used my little cheap presure washer on it(not to close) and so far its holding up well. i will remove it as i can get $$$$$ for the paint or powder coat(right now im a little pissed off about powder coaters) but for that instant black out its good. i got some pics around here somw where an can get more. have fun
I did it to a few things on my bike. If you are planning on putting it over chrome, it doesn't stick too well IMO. It started peeling off within 6 months. I may have applied it wrong, but the nice thing is that it's inexpensive to recoat.
