There are so many private label products, many of which have been given great reviews by individuals and sponsers of these forums. Realistically, what is so different from these products compared to waxes and polishes available OTC? I have used OTC Meguairs, Mothers, Liquid Glass, and just about anything else out there over the years, all with very good results. I have also used many of the PL products including AIO, UPP, Poorboys, Pinnacle LS, Zymol which we all speak of so often with little or no difference in end result. I have also tried products from Warner Chemical, Lanes Fastlane, and Detail King. In a fair comparison is there an independent review published by a non affilate testing lab evaluating shine, durability, swirl removal? Consumer reports usually publishes a review of OTC car products, and the results were surprising. I believe NuFinish finished at the top of the pile, with many of the multi-step products providing little or no advantage in shine or durability. In the end all of the products OTC and PL achieve great results. Whats unfair and bias are reviews based on reapplication at 4 week intervals. It really doesn't speak toward product durability for a typical application. It also doesn't speak to geographic and environmental differences. A car polish popular for the Florida and Calif climate, may be junk and fall short in the MidWest or North East. Being fair I can achieve the same great shine and durability with OTC products if I follow it up with monthly reapplications also. The real test is application on a daily driver which is exposed to the elements, and washed infrequently with no follow up reapplications as most consumers tend to do. After a month or so you will guickly be able to discern which products are the real keepers and truely live up to there expectations. Not a single carnuba product I have used lasts more than 6 weekly washes without reapp. Sealents I have gotten maybe 3 months before maintainence reapp. Common sense is telling me any car can look great if washed weekly, and waxed every 4-6 weeks regardless of product. In the end it's all about personal preference, cost, and time I suppose. Most of our product observations are based on opinion lacking any real scientific evaluation to the contrary.
