My least favorite of Track's polishes. I liked Clean N Shine better (now discontinued). Delayed Reaction does as advertised - delays the reation and tames the backend. Definitely, helps to deaden a ball for drier conditions. To remove the Slip Agent in Delayed Reaction and return the ball back to normal, I have had sand the ball. So be sure you want to tame a ball down before you apply.
Clean N Shine delayed reaction and didn't tame backend quite as much. Also, it was easier to remove (usually cleaning with Clean N Sheen was adequate).
Magic Shine assists ball getting through heads but leaves backend strong.
