As of now there is no glossifier on it, I'm still debating whether or not I want to do it. I kinda like the Matte Black look...
To prep it, I just used Windex and some Costco paper towels! Lol Spent about 5-10 minutes cleaning each rim. That was the hardest part! I recommend if you do it this way though that you also have a air spray can handy to get off the little extra pieces of lint/dust. I just blew it all away and got light headed every time instead! After that, I took a garbage bag, cut a long line down it, then wrapped it around the brakes/caliper parts, worked great! No over spray anywhere! Even if there was, the Plasti Dip just rubs right off...
I'd say total time including prep from start to finish was maybe 2-2 1/2 hours. Time flew by though, felt like way less!
One thing I also definitely recommend is to get the spray nozzle attachment to the Plasti Dip can! My fingers and for arms were pretty sore afterwards from spraying so much! Trust me, you'll want it!
