Anybody have any reports from using the DuPont stuff? I bought a can to use instead of the Chain Wax I had been using. The Chain Wax doesn't sling off, the DuPont does! There's a greasy streak across the centerstand, and inside the chain guard, but I've only used it twice (in about 1000 miles). Also, the chain got noisier, and is now to the point I need to replace it (12,000 miles, had 10,400 when I bought the bike). The chain has a few tight links that don't like to swivel. That's what is making it noisy since I started using the DuPont. They were tight before, but the DuPont apparently isn't as good as the Chain Wax
