[/quote]Didn't use the clay bar since it's still new and clean,[/quote]
I Zainoed my yellow last September when it was just a couple of weeks old. I also considered not claying, but when I tried Zaino's suggested test (run your hand over the finish inside a sandwich baggie) the roughness was easy to feel.

After claying a small area and rewashing with Z7 the finish was far smoother. It's well worth the trouble to claybar IMO, especially since you really only have to do it once. After that your mulitple coats of Zaino will protect the finish.

Putting multiple coats of Zaino, or any high performance wax or finish, on an inadequately prepared surface just didn't make sense to me. YMMV I suppose.

 

That's a reasonable question....until you actually try the Zaino.

I had never even heard of Zaino until joining this forum about a month ago. After reading about their products here, I ordered a bunch of stuff, and spent most of a Saturday doing a full treatment. Washed with Dawn, Claybar'ed, washed with Z-7, applied Z-1, then followed that with 2 coats of Z-2 w/ZFX. To put it bluntly, I've never achieved such an incredible looking finish, and I've used/tried a whole pile of different waxes and surface preps over the years. The Zaino may not be the best available, but it works pretty damn nicely, is easy to apply and remove, and all at a price that is reasonable (to me, anyway).

Went over the interior vinyl last night with the Zaino leather conditioner. Yes, I thought it odd to use a leather treatment for vinyl, but that's what Sal at Zaino recommended that I use when I emailed with the question. Worked great. Plus, it smells good too. :D
