For me, Optimum polishes, specifically Polish II and Finish, did not live up to the hype. In my opinion, I did not find them to be good at all. Now, I was working on my soft black paint, but the Optimum Finish and a LC Black and Blue pads still caused micro marring.
Now, their main benefit comes from applying Opti-Coat after, but now I'm reading that Hyper Polish is really the recommended prep for Opti-Coat, since consumers, save professionals, do not have access to the Opti-Coat primer (if anyone can enlighten me for the reason why this still is I would be very thankful).
I've used Pinnacle, Wolfgang (Menzerna), Menzerna, Meguiar's polishes and feel like they all outperform Optimum polishes. It's not a SMAT thing, since I get good results with Meguiar's M105/205, it's just for whatever reason, I feel like they're overrated polishes. I finished out the bottles otherwise I would have sent them to someone who enjoys their polishes.
