Ehh, Zymol is alright I guess.
There are better waxes out there. Any of the Meguiers products are good....their 3 step system, gold class wax, and the new NXT work very well.
If you have a Harley Davidson store near you, go in and pick up a jar of S100/P21S wax. It's about the same price of Zymol but the results will blow Zymol out of the water....Trust me.
