OK, must say, love my cars and want them to look great. In the last decades, I've used a huge array of the waxes out there, in the never ending quest for the perfect shine: Meguire's, (many versions) Turtle Wax, Zymol, Liquid Glass, Future 2000, Black Magic, Rain Dance, 3M, Turtle Wax Ice (paste and liquid), Turtle Wax Black Box, Mother's, Color Magic, etc. Liquid, paste, carnauba, synthetic, carnauba/sytntetic, cleaner wax, cleaner polish wax, polish wax, clay bar system, liquid clay bar. And those are just the ones off the top of my head!With that said, here are the conclusions:- I've never noticed a real difference between most any of them with respect to how the car looks after I've applied them. Put them on and the car looks great. This applies to the true waxes - the quickie things like Turtle Wax Liquid Ice, which isn't a wax at all IMHO, being the exceptions.- For most all of them, if you look at on line reviews, one will say it's the best and greatest, the next will hate it. So, VERY subjective.- Seems the more it costs and/or the more aplication effort involved, the higher it rates and the more staunch the opinions. Think there is a HUGE self fulfilling prophecy going on here;) Liquid Glass was expensive and a huge pain to apply (it looked just like any other I've used), yet it is rated 5 stars by most.- Carnauba provides the strongest protection against physical damage by stones and road debris. BUT is harder to apply and least durable over time.- Synthetic provides the most durable protection against the elements. AND is easy to apply.- God help me for saying this, but I can't tell a huge difference between a carnauba and synthetic wax job - both shine beautifully.That said, the goals of waxes/waxing is: Great shine, durable protection, less work, less needed yearly applications and reasonable pricing.So, here is the secret formula for those goals:1) Wax twice a year.2) Apply a carnauba/cleaner wax coat3) Apply Turtle Wax Ice PASTE coat - this is a good synthetic, but it's real advantage is that it is CLEAR. Not only does it not leave ANY white residue, but it can and should be used on all surfaces of the exterior - paint and PLASTICS. So, it is fast to apply/remove and it makes plastics look brand new.To the review of Nu Finish, it is a fine synthetic with the advantages of being highly rated for durability by "a leading consumer magazine" (as was Turtle Wax Ice Paste)and being easy to apply and remove - can do a whole car in like 45 minutes. BUT, it leaves the hated white residue, especially on plastics.  We're it not for that, I would have given it 5 stars - like I would most any reputable wax product out there.....
