This stuff is way too thick, so hard to work with. First tried with a foam applicator, like directed, but once it soaked into the foam, it was hard to get out of the foam and onto the tire. It also would not get into the small lettering and "style lines" of the tire. I ended up using a toothbrush too, 1- not waste product by overly saturating a foam applicator, 2- force into all the small areas. This added an unreasonable amount of time to the process. It also left the tire with a blotchy (too glossy) look, so I followed up with a wipe down with a microfiber. This was a learning curve also.... wipe too hard, have "dry" streaks in the finish, use more of a buffing type action to get an even look. But, that left excess product in all the small lettering and style lines, so those parts ended up looking shinier than the smooth parts of the tire. Longevity? Don't know, don't care.... this stuff would need to last 1 year, for me to even think about using again! I doubt it will.
