I have been using durashine auto polish and car wash now for 3 years and it works very well and has got to be the quickest way to make you car shine. All you do is buff it on and rinse it off with the hose. To wash and polish my car, it only takes abou an hour, and it shines just as nice as any other wax or polish. I don't know if it protects your car from the sun as well as they say in the infomercial or if lasers cannot penetrate it (also in the infomercial), but the selling point for me is the short amount of time I can have my car washed and polished. I am not in anyway employed by duralube or durashine, I just find it to be a good product.
