i gotta agree with 2K7MS6, The only thing i might add to his comment is that when you do wash your car, make sure you clean off the old tire shine completely with a soft brush, soap and water, or it will work against the new coat of shine you are about to apply during detailing.I've never been a fan of tire shine personally... mainly because after 2 days it looks brown and nasty and it gets all over the wheels and fenders. But that being said, I broke down a few weeks ago and got some Black Magic Titanium tire shine. The stuff is GREAT. It goes on nice, doesn't sling at all and lasts a long time. And even after a couple washes, it doesn't turn brown from dirt and dust. Just kind of goes away. I've been pretty impressed with the stuff!
