This is the frosty Blue Streak (Sally Hansen) from their Insta-Dri collection. It's opaque in three coats (I only had two in the pictures below and I could see some discoloration that was my nail peeking through till I added a third. By that point, I was too lazy to take pics of the third coat ;p
Application is easy but it does present brush strokes so if that bugs you, do beware. Otherwise, it dries at a rapid pace and is a gorgeous bright blue that could work for most seasons except maybe fall.
