Saved my wheel lights!
Size: 1 Pack
Style: Red (Permanent)
I recently installed some lights that go around my wheel wells on my jeep. I noticed one day after going over a bump that I had a horrible metal on metal sound in my passenger front wheel. Upon inspection, that bump knocked the screw loose and it was rubbing the back of the screw against metal while I drove. I tightened it, and within two days it was loose again. My friend suggested this product and now, so do I! I did two coats on every single screw used on the 4 tires (12 total), with dry time between each application. It’s been almost 3 weeks and not a single loose screw yet! I’ll be keeping some of this on hand forever now. A little goes a long way and it works!
