Well everyone knew I would do it. Used about 1/2 oz of Opti-Seal and one dose of polycharge. Shake well. Apply as usual. Works EQUAL to non PC OS. Durability, I'll never know because the RX8 is a test rotary rocket for MDRX8 NASA Division. I would NOT recommend Polycharging OS. There appears to be no gain in performance except maybe a little less streaking when you over apply (as I always do) OS. Well what next? How about polycharging Autoderm.....Hey that may work better.....Anyone with products for me to try on the Rotary Rocket please send a sample and I'll try it. ZOOM-ZOOM
