Just used the Prep & Shine on both my mountain bikes. They both look really clean with a brilliant luster. It leaves the surfaces slick and clean feeling. I can't wait to get a ride in to see how well it propels dirt from the bikes. After I get a couple rides in, I'll post another review, but so far I'm liking what I have seen and plan on getting more.
Easy to use, looks great, quick application
Spray it on a towel first to make sure you don't accidentally spray onto brake levers and grips.
