I use this product. Not the clay but the sealant. It isn't my favorite or close to it, but it has it's place. If someone will wax their car with it and tell me what they think I'll send you a sample. One person who will be unbiased. It leaves a super glossy surface, it's not very shiney at all. It also leaves a powdery residue, but the powder is very easy to deal with. It goes on easy and comes off easier. If you cut it in with a rotary then apply a second coat you will get very long durabilty. I have a couple bottles left and I'm planning to not re-order it, because of the new Zaino which looks like it has unlimited potential. I will say this, I have many customers who like this stuff, and my girlfriend likes this stuff and she can choose anything I have. If someone likes the sample I'll sell them a full bottle or trade if they want. If not, just tell me what you think, it's a pretty good product. Tell me if your interested, I'll check a couple of your last posts, then email you and you can reply with your address. Only people who will try it soon please reply. It is an exellent Winter product because it goes on thick and stays on thick!!! If I was going to a winter state for months this might even be better than collinite for protection.
