I also got good results from Wolfgang. I prepped my black Grand Prix with SSR2, then applied the polish with a PC and a white LC pad. It left a very smooth and slick surface and removed very easily. I left the sealant on for about an hour or more since I had eaten dinner and such. It went on and off very easily with no streaking (except for my hood which streaks everything).
The only problem I have with it is that it is a dust magnet. I had to take a car ride today and had just applied everything yesterday. The salt dusted roads here made car my car look white. I even could make out the pattern that I wiped it off in. Hopefully some rain or a wash will remove that probem. I'll post pics when I get the effort.
Yeah, it does seems to become a lil dusty so i think i am going to try a carnuba as a topper next time and see if that helps! the dust isnt bad on my mom's car though - nothing a normal weekly washing wouldnt take care of.
