I have a polish to show you that I know you've seen a bit of lately, but I thought I may as well put my two cents in! I have 'Oh Splat!' from KB Shimmer for you...
As I said, two coats of opaque goodness. Formula on this was surprisingly easy. It was pretty thick but as you only need two coats, it didn't bother me at all.
I bought 'Oh Splat!' from Harlow & Co. for $9 USD.
