This is a quality product. I've used it for 30 years and have never been disappointed. One bottle will last me several years. Several weeks ago I used it, and again I was very satisfied. But, I decide to try the Turtle Wax ceramic coating afterward and WOW what a result. It has only been a couple weeks, but the ceramic coating has amazed me. This product is great, but the ceramic coating will amaze you even more.I have used this for years. It is easy to use but with light colored cars it is easy to use too much. I find less is more and apply about a nickel sized amount for a couple square feet. I will apply to say half the hood, do the other half and then wipe off the first part. If it feels sticky on removal I will wait a bit longer. If it is dry it usually just wipes off with little friction. I use a microfiber cloth to remove and buff (a little buffing helps). I also usually apply on a cool car in the garage, and their website recommends to apply 2 coats. It has usually works well on my daily driver. I’ll pay more attention to how long this location lasts and will update. For the price it is not bad at all.have been using this since it first came out over 20 years ago. yes it lasts a year, and I wash my car every week. in july on a 95 degree day, someone exoded a coke on my paint and it sat on the sun for most of the day. when I got my car home I sprayed it with a hose and the paint looked like new and still had that smooth,slippery finish. only 8.00 and I'll buy it as long as they make itThe polish went on very easy and came off easy. After a couple of months it is holding up well. However, doing this once a year means I will be leaving this bottle in my will. I would really suggest you purchase this for the use of your family, car club, etc.Although it does not provide the deepest shine, it provides a long lasting finish that has water beading months after an application. Prefer to use this in the Fall before heading into the Winter months.Doesn't seem to last more than a couple weeks. Then you need to clean your windshield good at the car wash or with a pressure washer than reapply. Goes on in minutes. It's cheap and easy to do. I think a bottle would last a year if applied every 3-4 weeks.Have been using for some time, started back in the seventies! This was a great price and does a very good job of protecting your painted surfaces and GLASS! I use it on all my rides, bikes included. Leaves no white wax traces behind! Its a good product, and one of the few that comes through over the years.I use this product as a sealant in conjunction with a spray wax for detail work. Nu Finish lasts easily over a year, with cars that are even parked outside that long still beading water. The product doesn't dust too much and is very inexpensive. It can be a bit difficult to remove from paint if buffed after a longer period of time, but once off, the results are great. Have been using for years and will continue to do so.I have been trying product after product with no real success. Some seem to work but take too long to scrub off and last one wash. I got this and tried it today. I am so impressed, what a shine and flakes off cleanly when wiped with the dry cloth after. I did my truck (6 years old) and my wife’s car and still have enough to do another if I needed. Maybe I will do the bikes haha. I don’t know about longevity yet but if it lasts longer than overnight like the rest of them I will be happy. Try not to get any on the vinyl, comes off with a little all purpose cleaner but save yourself some aggravation. Thank you for a great product.After killing myself trying to wax my black benz with a hard Turtle Wax that was next to impossible to buff off, I went looking for a an easier wax. I remember the commercials for this Nu Finish wax from the 1990's.. something about a junk yard car looking like new. It arrived and i wiped it on with a wet cloth and let it dry to a haze. Then I prepared myself for some hard buffing....and was shocked at how easily it wiped off. It took next to no effort to wipe off the dried wax and then WOW such a perfect shine. My 2013 black benz glowed like new and i got compliments on its looks immediately. This is by far the best and easiest car shining wax on the market.I’ve been using this product for over 30 years. It’s easy to apply and remove with lasting results that survive the drive through car washes. I tend to apply twice a year - even on my windows. On our older car, the first time we applied this product, it pulled out the oxidation from the years of neglect and completely revitalized the paint finish, shine and bright as if it was just painted. Does not build up like other waxes— this is not a wax! My vehicles alway got loads of compliments on the shine.This is my first time of using Un Finish Liquid Polish. Last time I used Un Finish Cream. About two years ago, I found small orange dots all over my car's body. That's how I started using polish. I used Un Finish Cream once a year and it was good for a whole year. Since I started using polish once a year, those orange dots didn't happen anymore. One box of cream is good for two years. I drive a SUV. This year, I bought liquid. Liquid was easier to apply but the result was the same. My car looks like a new one, shiney and smooth. I also use the liquid to erase the light scratch. This time I used half of the bottle. So one bottle is good for two times too. I love Un Finish polish and recommended them to my friends.Works great on the windshield to stop wiper squeaks. Apply a coat, let it dry, rub it off and repeat 3x. You'll be able to run your wipers dry after that.
