Having some experience with spray detailers, I had an idea what to expect. Basically some gloss, a slick surface, and short-term protection. There is some controversy regarding whether water beading is a sign of good protection, but I won't get into that. What water beading (or sheeting) does accomplish is it at least shows the presence of product.There's another way to show presence of a car wax/sealant that a car detailer showed me years ago, and that's the steam test. It doesn't measure protection, per se; it just shows the presence of a product so you can see how uniformly it covers an area, how easily it comes off, etc. Basically you coat some product onto a bathroom mirror and allow steam to build up in the room. Areas of the mirror coated in wax/sealant will have a uniform layer of steam that is different from untreated areas. It won't repel steam, the barrier causes tiny water droplets to build up uniformly, (appearing as if there is 'more' steam there). You can try it yourself and see what I mean.I bring this up because after noticing that the V7 just didn't seem to do as much as other similar sprays (the gloss was fair but not very good, and I didn't notice the extra water beading that other spray detailers provided at least short term), I wanted to see what it was leaving behind. I did the test, using the V7, along side a couple other spray detailers.The results surprised me. The areas treated with V7 left very little behind, with some streaks of presence. I also applied some Meguiars UQW and Turtle Wax Ice, both of which showed solid coverage (and the TW had remarkable durability to removal, incidentally).  When I applied two more coats of V7 over its area, it began to show more signs of coverage, confirming my results: This appears to be an extremely watered-down detailer, high in alcohol so that it "flashes" (evaporates) quickly. It came completely off with a bit of soapy water, whereas the other products actually were rather stubborn to remove.I give it two stars because as a quick detailer, it's fine. It will clean off fine dust and fingerprints, and leave a wee bit of shine. In the gallon size the value is fair, but $18 or so per bottle is silly, seeing as how it has just about zero sealant properties and even the shine it leaves is inferior to some $8 spray waxes.I've heard that CG is hit and miss with their products, but V7 is generally regarded as one of the hits. In my experience, it is not. Maybe they make some good stuff, but this isn't it. I don't want to judge the company by one product, so I'll give another one of their products a try, probably.  I gotta say, they do a really good job with graphic design on their packaging; especially the "vintage" line. I digress.
