Sorry I missed this just unitl now. But I use ALL Adams Products and use the PC for all my buffing and use the Adams Wax and Adams Machine Super Sealent. I have to say it is the best products/ customer service I have ever delt with. The wax feels like butter once done and last for a very long time (if you keep the car clean) and don't use the automatic washes that much.

I second this comment regarding Adams. Use it on my vette, Yukon, and wifes Sorrento. Will never use any other product. In fact, it smells so damn good, I want to eat it users of Adams know what I'm talking about!
