Yeah I have used the spray, 3 times so far, bottle still has a bit left. The first time I did ti was on the way back from summit getting my bottle filled and some tailpipes, yeah we got that huge tailpipe box in my back seat, top down lol.
I hit it in 3rd at 55 and I spun tires for about 3 seconds then took off like a damn rocket. That was the single most badass moment I have had in my car!
Edit: This whole project has now been put on the back burner. We had an unexpected death in the family. My mom's aunt, like a grandma to me, fell and hit her head this morning. She was only given 2 hrs to live and she died at around noon. Funeral is friday and sat. I don't even know when I'll have time to do anything, not like the car matters right now.
