Their "Rubbing Compounds" today usually have a grit number on the label, to the effect, "this compound removes scratches of 1500 grit and finer". It can be 1500 grit, 2000 grit, whatever.
Finesse-It II, I believe does not have a grit level specified on it. I also believe it contains some abrasive to smooth out the surface, because it puts a shine on things, almost too quickly.
I use the Marine version, usually intended for fibreglass on boats. So I assume it is slightly different than the "standard" version meant for paint finishes on cars. Both are very fine,so I assume, again, they''re in the 3000 - 4000 grit range, if it can be said to have a grit range. (Don''t assume that.) Both indicate that they do not contain silicone. SO I feel they''re safe to use on bowling balls.
I make sure a ball''s surface is at or just below where I want the grit to be before I apply Finesse-It II. Actually, since starting to use Valentino''s Snake Oil, I don''t recall the last time I used Finesse-It. It ain''t cheap.
