OPI's Push and Shove is the most unique polish I've come across in a while. To me, it almost feels alive like a crackle or texture polish. Once layered over it's special base coat, the silver colors smooths itself out to give an almost chrome finish. It's highly pigmented (this is one coat) and very reflective. The instructions say to not use a top coat, but since without one the polish is not guaranteed to last past 24 hours, I took a risk and tried one---no major differences were found, so TC-away, everyone!
