As the title of this post states, yes, I adore Rainbow Connection by OPI. I adore it so much that a while back I did two manicures in a row using it as a glitter top coat. How very creative of me.
First I used it on top of Essence Color & Go choose me!, and then I layered it over OPI's Planks A Lot from the Pirates of the Carribean collection.
I also tried out the Sally Hansen Diamond Flash fast dry top coat. I like it, but not for dense glitters. For those I prefer Sally Hansen's Insta Dri or Seche Vite.
