I used 3 coats which were enough for full coverage. For base coat, I used GOSH Fix Base #565. I believe it has been discontinued, unfortunately, but I've read that other holographic base coats work well.
I'm very excited to have Flash Black in my collection! I can't stop staring at my nails :)
I purchased Flash Black from Aveyou.com for about $15. At the time they had a coupon for 20% using code ALLCHIC, or $25 off $100 using code GIMME25. You can also order it directly from Layla's website or Ebay.
Thanks for stopping by. Happy Polishing!
