IIRC, Columbia used Finesse-It II on their reactive pearls until they introduced the Degree system back in the mid-to-late 1990s.
I use Finesse-It II on rubber, plastic, urethane, and weaker reactive balls. As for stronger reactives and particles, I try to stick to the manufacturer's recommendation.
