There are a lot of differences between the two. First its important to note that unlike some companies that make two similar products and call one "pro version" this is not the case with CarPro's CQuartz coatings. UK and Finest are two very different products with different chemicals using different modifications and volumes of nano tech Si02 and other ingredients.

Now, to answer what are the differences that you would see or find proof of without looking at MSDS.
1.- Application could not be more different
2.- Finest has superior stain resistance than any coating we have tested including UK. (See expanded story on this feature at end of my post)
3.- Both have excellent gloss but Finest has more gloss then any other (even slightly higher than UK).
4.- UK has an equal "richening" affect equal to Finest
5.- Durability: Finest wins the race here as well although UK is going to last as long as anyone of us "How does it look" types would need it to. Unless it literally only sits in the garage... over the course of 2-3 years eventually you will want to have at least a light polish on the vehicle and add another coat. The truth is there is no such thing as permanent anything... its a poor word choice for something man made... Without cleaning and/or maintenance the environment and mother nature will eventually win! Steel rusts, concrete disintegrates, weeds and bushes will tear through concrete if left to do so. Sunshine and the atmosphere oxidize all substances in one way or the other. The key to us is: How long does the coating help keep the vehicle looking good? The answer is longer than anything else. It should be noted you must care for your vehicle! Its not a license to abuse. Instead it is a tool that with proper knowledge and products will keep your car looking beautiful for years.
6.- Hardness (Resistance to fine wash induced marring) is stellar with both products. Even in UK testing we have some real world test, 6 months after application - one side of car with UK and the other with only wax and sealants and you can literally see the difference in the few ultra fine swirls on the uncoated part.
7.- Finest has more slickness feel to the fingers than UK (for what its worth UK application should include Reload which adds slickness)
8.- Finest sheds dirt better than anything else we have used but UK is NO slouch! We tested it side by side with a competitor ceramic coating that sells for well over 100$ just for purchasing a bottle of the product and CQuartz Uk beat it visibly.
