### ⭐⭐⭐⭐⭐ Don’t blink, this stuff works fast and good!
*by T***3 on May 20, 2025*

Dang, this stuff works so fast you better not blink!! The beauty ring bolts in my bronco were kind of messed up from removing a couple times so bare metal was showing through the black. I poured some of this stuff on a bowl, dropped the button head torx bolts in and Shazam! No more silver was showing. Incredible. They look fantastic. One difference from the stock bolts is these come out with a matte black finish while the OEM Ford bolts have a shine on the black. I waxed these baby’s up and they look very, very close to the stock ones. Nobody would ever know. I got so punch happy I took my eyeglasses apart and threw the frames in but no go, this stuff only works in steel not aluminum. Oh well, can’t win ‘em all. This stuff works really well, if you need to blacken some steel hardware…get you some!
