I doubt C&Smooth will take a ball to 1500 grit from 400 grit sanding. I use C&SMooth and I'd never even think to try such a thing
Clean and Sheen will not necessarily leave a ball at 600 grit, either.
If you want to use C&S to take a ball to 1500 grit, I would suggest sanding with 400 grit sandpaper, then 600 grit then 1000 grit, then 1200 grit, at a minimum. You can then use 1500 grit sandpaper and C&Smooth will smooth out the sanding marks left by any sandpaper. I've done this a lately
(Aside: Clean and Sheen is meant to remove sanding marks left by the process of smoothing out a plug, which usually involves routing and then some rough sandpaper. It will usually smooth out 400 or 600 grit sanding marks and, when you use enough C&Sheen, for long enough time, with enough pressure on a spinner, you should get close to a 1000 grit or compound polish. It will NOT be a gloss polish, but halfway between a matte finish and a gloss polish.)
So if you do a thorough job with Clean and Sheen, you can probably apply Cleanand SMooth on top of it to get close to a 1500 grit matte finish. HOWEVER, do not rub C&SMooth too hard or too long or you cna get a light polish on it.
