Yes, I tried to wet sand it after a couple of days, and got those streaks. I was disappointed. However, after the first wreck (Several months later), I sanded it, to repair the damage, and it didn't do that again, so I wet sanded the rest, and it looked great. It reflected so much, that I'm still surprised I didn't get some kind of ticket. I now have sandpaper, and Micro Mesh down to 12,000 grit (< not a typo!) I'll pick a spot to shine up, and post pictures.
