I find that the Opti-Coat Pro is much easier to apply than the consumer version. Maybe I've been applying OC 2.0 too thick, but I always ended up having to chase down streaks that wouldn't flash off over 15-20 mins. It could have also been the temperature I was applying it (high 50's, low 60's). OC Pro flashes a lot quicker and is easier to apply in a shorter timeframe, and I find that I have to chase down less high spots.
OC Pro has a shorter working window and cures faster so if you're unfamiliar to the product it may be best to play around with the consumer version first (OC 2.0).
