For a couple of bucks, I didn't expect magic from Sinful Colors. But, I have found that using either a) a good base coat, general SC color and good top coat or b) a general SC color and a good topcoat is key. If I wear the polish on its own, the wear time is maybe two days. If I increase the layers, I also increase my wear time to nearly a week. Sinful Colors' base coat and/or top coats suffice, but I usually seal the color with a slightly more expensive brand.
