Pros: Works great, is easy to apply, lasts for a long time, inexpensive.
Cons: Not exactly a once a year polish, somewhat difficult to clean off certain surfaces.
Nu Finish liquid car polish is a must for anyone who wants to protect and improve the appearance of their car. It is a white liquid, about the consistency of white out, that comes in a 16 oz bottle. You simply apply it with a clean cloth, wait for the liquid to dry to a white haze, and wipe off the remaining residue to reveal a clean and reflective surface. The product comes with a money back guarantee and will not scratch your clear coat finish. My favorite aspect of Nu Finish liquid car polish is that you really can apply it in direct summer sunlight and it will still work!
Claims and Guarantees by the Company:
Nu Finish comes with a money back guarantee to "shine and last longer than any other car polish or treatment, regardless of price, or return unused portion to place of purchase for full refund." I have never felt the need to even consider activating this warranty, as I am very satisfied with the results every time I use it.
Another claim made by the manufacturer, Reed-Union Corporation, is that "Nu Finish will bead, shine, and protect for a whole year...even after 52 automatic car washes." I don't have the money to run my car through 52 automatic washes, but I can say that the shine and beading (rain droplets appear like beads of water on top of the surface of the cars paint, rather than puddling) lasts anywhere from 6 to 8 months. I can say for sure that 2 to 3 automatic car washes a month do not affect the shine or beading. The Winter here in Wisconsin tends to take it's toll on the polish, as road salt and ice cause degradation, but there is still significant shine left each Spring when I apply a new coat of polish.
Lastly, I can attest that the polish has not damaged the clear coat finish of any of the five cars I've used it on. It does seem to protect against road chemicals and oxidation to a point, but once rust spots start to develop, the polish isn't going to be able to stop the oxidizing process.
Typically I can polish 3 to 5 cars/times with one 16 oz bottle of Nu Finish. The cars that I polish are both over 17 feet long, so if you have smaller vehicles then you might be able to squeeze 7 coverages out of a bottle. You don't have to go overboard applying the polish, a small amount can cover half a hood or trunk lid on my Lincoln Town Car and will still work fine. There are no real guidelines for how much polish should be used to cover a certain size area. The only instruction is to work on one section at a time. I have found that filling the cap of the bottle with polish will cover an area about 12 to 15 square feet.
The manufacturer's directions are very simple and as follows:
1. Wash and dry car
2. Shake well and apply with a damp cloth, one section at a time.
3. Let dry to a haze and wipe off with clean, soft cloth.
Then there's the catch, for maximum protection, apply second coat in 30 days. Whats that you say? Second coat? So its not really a once a year car polish after all.
I don't always apply the second coat and the polish still seems to work fine for 6 to 8 months, depending on the weather. Generally I apply a coat of the polish in the Spring, and another in the Fall just before Winter and this keeps my cars shiny all year long.
For best results, use a swirling, circular, motion when applying and removing the coat of polish. Using different cloths for application and removal is important as one has to be dry and the other damp. The damp cloth for applying the polish should not be too wet or the polish will not work effectively. Trial and error is the best way to figure out how damp a cloth to use, and how much polish is needed. You can't put too much on, but you can apply too little polish, though a thin layer is usually sufficient.
Polish Vs Wax:
I had tried multiple products to make my cars shiny including various waxes, then I found Nu Finish. The polish is easier to apply, it dries faster, there's no messing around with a buffer, and it yields longer lasting results. I tried some Turtle wax on my Lincoln and it made the finish shine, but it also left white residue that lasted for months in hard to access water drainage cracks. I hate trying to use our messy and hard to control buffer and Nu Finish completely eliminates the need for that cumbersome device. In the end, the greater hassle and time with the wax yielded me only about 4 months of shine, 2 months shorter than the polish!
I polished the windows of my car with Nu Finish and they stayed water repellent for about 2 months, try that with wax (do not try that with wax, not a pleasant experience).
Best of all, there is no shade near my garage, so the ability to polish the car in direct sunlight is a definite plus. You do have to be careful to remove the dried polish once it turns to a white haze quickly, or it will take more effort to remove as it becomes sort of a sticky solid. This is not a problem in shaded areas, but I have seen no difference in end results between polishing in sunlight or in shade with Nu Finish. The polish is water repellent immediately after drying.
Nu Finish is a mild eye irritant and should never be frozen. It should not be used on vinyl, metalized plastic trim, simulated wood, rubber, or flat paint. I accidentally got some on a rubber window seal and it caused some discoloration. It will pull the black color right off of rubber and simultaneously ruin your application cloth, and it leaves a white streak on vinyl. After drying, the polish is difficult to wash out of clothes and other materials and fabrics. The bottle is kind of cheap and will break if you drop it, spilling the polish everywhere. It's kind of like cleaning up ranch dressing that begins to harden and no, it isn't fun.
I find that applying the polish will result in a shiny and smooth appearance for your car. It will not remove scratches, but the visibility of minor surface imperfections is greatly reduced or eliminated. The polish makes your vehicle's paint look newer and more vibrant. Minor fading in the paint job is also eliminated, as the car's color deepens and blends together with this product. There is also a great reflective quality to paint treated with this polish, I can see the sky reflecting in my hood almost as if in a mirror after application. If your car's paint is very faded, scratched, or peeling, then don't waste your time and money, Nu Finish is not a substitute for a new paint job. If, however, you want to maintain and brighten a decent paint job then this product works great.
The bottle may be cheap but the contents are very durable. As I mentioned earlier, I apply the polish twice a year, in Spring and Fall. During the Winter, I store the bottle in the basement and by May when I need it again, the polish still works. The label warns to keep from freezing, but it still works after accidentally leaving a half empty bottle in the unheated garage all Winter.
Nu Finish is a great and inexpensive (about 12 dollars) way to polish and protect your car. It goes on quick and easy, and works for a long time. The only down side is that it is hard to clean up if you apply it to the wrong surface or spill it, and it is not really a once a year polish.
