Used to hang with a car club a while back that swore by the stuff. One of their guys was suppossed to be a distributor and claimed he was one of the only sources for the stuff. When I suggested doing their cars with my stuff (all 3m at the time), they laughed at me, and told me ibiz was the best ever.
I got some to try out on my car (then a, 91 civic that was well maintained by me), and I was totally unimpressed with it. True, it did clean things a up a little, but it did nothing to enhance shine or gloss. in fact, I hit the the hood with my Fill N Glaze on one side, and then some Mother's liquid carnuba on the other side, and left the ibiz in the middle of the hood. The sides with the glaze and carnuba looked a lot better. When I showed my results to the guys, they just dismissed it, claiming that since i work in a body shop, that I probably screwed around to make the ibiz look bad.
Just to show them in person, i prep-soled the whole hood, and did the process all over for them with a twist- this time I combined the glaze and then topped it with the carnuba. This made four differnt sections that had product on the hood. The section with ibiz looked ok, the section with just the glaze looked good, the section with carnuba looked better, and the section with glaze/ carnuba looked best. Even after they saw this, they basically dismissed what I had to show them.
Shortly after, I was dismissed from the club. I have no doubt that the president (who also happed to be the guy pushing this stuff) was responsible for me getting the boot. I'm still cool with most of the guys, but after getting kicked out, i pretty much stayed out.
Personally, I would sooner use my gold class liquid wax than use that stuff. At least the gold class will give a decent shine.
