And I have used many, many different waxing and polishing products on cars. One I used religiously for years was NuFinish, and excellent polymer polish that can be applied and removed easily in the scorching, Florida summers I work in.Late last year (2009), I discovered a product called Meguires Cleaner Wax which is a carnuba-based polishing product, and I moved on from NuFinish (but always keep a bottle of NuFinish in your supply cabinet for those BLAZING hot days though). That said, Meguires cleaner-wax adds a deeper, wetter shine than NuFinish but does have it's limitations in removal in the hot sun, especially on darker color paint jobs. You have to ploish section-by-section with it.Then I came across Chemical Guys' Butter Wet Wax, and just let me say, when I detailed several of my customers' vehicles, they were extremely impressed with the finish, and I was impressed with the way it applied and was removed in the hot sun.Chemical Guys doesn't lie, their Butter Wet Wax looks absolutely amazing, especially when it's applied over an already existing polish and/or wax job. It leaves a deep, mirror finish that actually looks wet. The darker the color the wetter the look. I tested Butter Wet on mine and my mom's car (both are white), but they still looked very, very good, but when I was able to use some on a few of my customers' dark-colored cars, I just stood back and admired the result.Try it.Buy the 16 oz. bottle first and test-try the product out and see how you like it and I believe you'll be impressed enough to go ahead and buy the gallon supply and you will probably come back for more. One 16 oz. bottle should easily be enough for 20 - 30 or more cars depending on size. It spreads evenly and doesn't take a lot to get the job down. Always keep your applicator pads just slightly moist-damp though, not heavy-damp or dripping wet, as I've found only moist-damp offers the best application because of the oils already in the wax.Also remember though, this product works better over an already existing polish job. On your repeat customers (or just your own car), I've found the Meguires cleaner-wax or NuFinish offer a great base coat and then the Butter Wax sends the shine to an entirely different level. Then you can just use a detailing spray a few times to gloss it out again until you use Butter Wet again.It's really an impressive product, and btw, I just ordered the gallon supply.
