I got the Z-16 Tire Gloss. It started raining today so I will check how it looks tomorrow should the weather clear up.

A couple things I have noticed since putting it on. The product puts on a semi-gloss - very light on the shine. The bottle's instructions did say you could add another coat if you want more shine. A pleasant surprise is that dirt doesnt seem attracted to it.

I'll post on the streaking or lack of tomorrow hopefully.
