Wipe it down and clean it like a mad man. You need to remove any/all silicone, grease, grime etc.. let by armor all or any other dash/interior cleaner you have used. Then find a plastic paint that matches. Ripping the dash out is a day job in itself. Good luck.
Kinda at a loss here. To me the sticker bombed lip on a black car just doesn't look right and those rims are just the wrong style and size to pull off chrome on our cars. But hey man if you like it than more power to you, that is what matters the most.

I've seen the commercials but the fact that Adam Carolla is on the show kind of turned me off to it. He just doesn't seem like a car guy at all to me. Based on your review I might give it a view just to check it out though.
If you already had 6 hours invested you should have gone ahead and removed that broken bolt too lol... would have been your best option so you don't have to worry about doing this all over again when/if it leaks.
