Two coats, Orly Bonder (base coat), Seche Vite (top coat)
Opaque in one coat, but I did two just for good measure. It's thick but not so thick that it will make a mess. I only had to dip the brush into the polish once to get enough to paint five nails, which is insane. It dries well. It has not chipped or flaked in a few days, but there is minor tip-wear (I type a lot). Excellent nail polish. ALSO it only costs 1.99 USD. Seriously.
