I called Poorboy's, and he said that it doesn't. Maybe it's like when Meguiar's, when they say stuff doesn't have fillers, but the polishing oils "just happen" to fill.
Here is some evidence:
It leaves the surface "too" glossy, smooth, and slick for such little polishing (I can pass the PC over the area only once)
When I used Scratch-X over a SSR1'd area, it left smudges that were impossible to buff out until I went over it with SSR1 again.
Surface is not left squeaky.
Anyway, I used SSR1 to polish an older Corvette with maroon paint, and I think it worked pretty well. The best thing about it is that it wipes off super easy.
