Really considering using Opti Coat 2.0. I've heard conflicting reports on prep, so I thought I would come straight to the source. Now, I've heard that if Optimum Polishes are used, just a damp MF wipe is needed. With other polishes, I have heard using power clean, dawn, or IP alcohol. I've also heard some use Car Pro Eraser.
Can anyone confirm the process if optimum polishes are used? Also, in your opinion, what's the best prep method if using other polishes?
