The polish itself wasn't particularly easy to paint on. Because of the metallic nature of it it was a little streaky and the brush is horrible. This was two coats of the polish, then I let it dry completely for an hour or so (it didn't take long to be dry to the touch) before I put on the scotch tape and used Butter London's PD Quick on the top to change the colour. I left the scotch tape in place for probably 2 hours before taking it off to ensure it was completely dry - and I wanted really crisp lines. I'm pretty pleased with how it turned out, but not sure how long it's going to stay chip free (it's a bit annoying not being able to put a top coat on to protect/smooth the lines!)
Have you tried any colour switch polishes? What designs did you do?
