I can't speak to the OC product at all, but I am glad to see some fans of ZAINO here. I've got to share a small testimonial to the ZAINO products. The following is my calendar notes from May 28, 2012:
"I waxed BOTH our 2010 Outback and my '99 Forester with ZAINO products, and it is embarrassing to admit it is the FIRST TIME I have used this stuff that I bought at least as far back as 2003! It has sat on the shelf for 9 years or more and had separated inside the bottle and looked questionable. I shook it up well and eventually it seemed uniformly mixed again. I used Z1 PolishLok & Cleaner and Z2 Showroom Car Polish on the entire cars. I tried to remove some bird dropping damage on the front of Debbie's Outback with bug & tar remover, but it didn't help. Then I buffed it hard with the Z1 cleaner but it stayed. Surprisingly, it was pretty much gone after the Z2 polish application and eventual removal. I did the cars inside the garage, and then let them sit outside to let the polish completely dry before removal of haze with a white 100% cotton towel. I was amazed at how easily it came off, free of swirls and streaks. It was a tough job mostly because I have NEVER waxed the Outback and it's been as much as 8 years since I waxed my Forester! I really worked to scrub it as clean as possible. It should be much easier on a repeat if I don't wait too long. The Outback looks GREAT, and the Forester is much better, though at 13 years old, it has a fair number of imperfections in the paint now."
Well, I have waited too long (haven't applied again since) but honestly, I am STILL amazed at how well one application of ZAINO has impacted the cars. It STILL beads up some if the cars have been washed (yes, even the old Forester paint, which blows my mind.)
The OC product might far exceed this, but I have to say, for the ease of application and the results, I'm a permanent ZAINO fan. I don't plan to spend lots of time reapplying things, and really don't wash our cars nearly often enough, but having tried a couple or more polymer products (which were largely a nightmare to work with) and Meguiar's wax, and of course, other waxes in the "old days," I've never seen anything that was as easy and gave as much bang for the buck as ZAINO did. I sort of choked on the price when I first ordered it, and then lazily let it sit unused, mostly because I thought it was going to be a tough job, like previous polymers had been.
I think I've talked myself into getting another coat on the 2010 Outback again soon...
