It also slightly reminds me of Deborah Lippmann's Hit Me With Your Best Shot. I sold that off, so I cannot do a comparison, but the finish and color is similar in my opinion.
I recently received a care package (RAOK!) from Jeanette of The Swatchaholic. (!!!!!) She sent along so many squee-goodies, I have some swatches for you coming up. She sent me two of the P2 Crackling top coats, Silver Blast and Gold Rush. These are both lovely. I decided to top my Black With Envy mani with Silver Blast, and I thought it was awesome!
I just picked up a couple of the new Sally Hansen Crackle overcoats, one of them being the silver - Fractured Foil - and it's more glittery/shimmery and crackles a bit better than P2. Being a silver addict and a big fan of crackle top coats, I feel like I need them both, because they're definitely different! Obviously, I haven't posted any swatches of these yet, but I will - in case anyone's wondering, the Sally Hansen Crackles are AWESOME.
As you can see, on my ring and pinkie fingers I applied the crackle a bit thicker. It's kind of a cool effect!
