Opti-coat is a coating not a wax. The problem is that is creates a layer similar to a clear coat and that it is no filling ability. Thus, you need to polish the car properly prior to sealing.

I can get the exact same results by washing my car with Dawn detergent, then clay bar the car (takes about ten minutes), then putting on one coat of Zaino All-In-One with an orbital buffer, then one coat of Zaino Z2. This whole process takes about two hours at the most and will cost me maybe $40 in products that will do several vehicles.
