I used Hydro Shine on my wife's black Mecedes every other time I washed it for about 1 year without waxing it once. Every time I used it, it looked "just as good" as if it had been buffed and waxed. For people that know Mercedes black, it's a pain in the *** to keep looking good(very soft). I was sick of spending all day polishing it, just to stay looking nice for a few weeks or a month. I haven't waxed my current company car(05 gray Mailibu - 70,000 miles) yet. I just Clay Magic it and use Hydro Shine once a month. The finish looks as good, if not better than when I picked it up from the dealer. When I get my next company car, I'm going to do a comparison with this product and other sealants/waxes. I'll bet that Hydro Shine will keep a car's paint looking newer, longer(if not forever) that any wax/sealant on the market. Using this product correctly and somewhat regularly is much more effective than waxing. For one, it's easier and faster.
