Not trying to hijack the thread.... I've tried Optimum polish with the cyclo and PC - both with good results.
A few observations that I've made after polishing 5 or so cars with Optimum:
-No dusting. Clean up is a breeze. This is a big deal to me, because dust clean up is a time consuming nuisance.
-Little or no hazing & micro-marring when using a cutting pad. I used an orange pad on the PC, set to 5.5, and produced a haze free finish on the hood of a black TL (and IMO the Acura paint will mar if you look at it wrong). I was really surprised that the polish removed defects and polished out so well with an orange cutting pad.
-It removes scratches & swirls very effectively.
-I've used Optimum along with other polish brands, with mixed results. For example.... Brand X SMR, followed by a pass of Optimum to clean up micro marring takes some work. In this situation, I like FPII a little better. Optimum as a stand alone polish (SMR & final polishing) works very well. As Scott said, the pad does the work.
I'm a big Menzerna fan (still am), but I like Optimum well enough to order it again. Optimum makes a very compelling case when you look at the product features, performance and cost.
If I had to compare Optimum to another product. I'd say it's similiar to using SSR2.5, followed up with SSR1, or IP followed with FPII.
