Really good stuff. Joe was good enough to take a little extra time and send some to me up in Canada. Not one to believe all on the Internet, I tried my own experiment. Firstly, I stripped the old wax from my boat. Then I did the port side with Pro Tec sealant, and the starboard side with the name brand polish that I have used for years. After my next trip, there was no scum line on the Pro Tec side, but the typical scum line on the other side. Quite impressed I was. The shine is also brilliant. Since then, I have done the entire boat twice, and about to do my truck. Definitely an excellent product.
