Lemme see if I can dig up some photos of what I found and used when I showed my G. Gliptone makes it, although slightly expensive, it shines like nothing I have ever tried before. I wouldn't recommend it unless this guy doesn't mind sling because this stuff will sling for sure. I suppose you can go back and give it a quick buff after applying and then let it sit over night to avoid some sling. It comes in a clear bottle, purple thick gel, and was around $11.
Forgive MISS HIN in one of the pics. Also, yes, I realize now I should have dressed the entire tire instead of just the sidewalls for the show as the tread looks crappy in pics without them being dressed. The rear tire was taken prior to final prep being completed. Although the pics don't accurately show how glossy this stuff is, all the other guys around me asked to borrow some because it makes the tire look like you can jump into it! EXTREME GLOSS and I have tried many products including th elong lasting tire gels!
Hope this helps!
