China Glaze "Rainbow" (China Rain collection, Spring/Summer 2001) White/Pink metallic"Rainbow" is an "oldie but goodie" of the China Glaze core line, having been around for 15 years and making the jump from non-3-free to 3-free."Rainbow" was a surprise. I honestly did not expect it to get to anywhere near opacity, as a lot of these older polishes were meant to be worn sheer, but "Rainbow" really wowed. It actually got opaque enough to wear as a pedi at two coats, building to a white base with a pink flash. If I was wearing it as a mani, I probably would have done three coats though. I'd say "Rainbow"'s just a little too opaque to wear as a topper though.What I Like:* China Glaze's brush and bottle are easy to use as always. It's also pretty cheap ($7.50-$8.00) for a high quality brand that has 14ml/.5 fl oz.* Beautiful polish that's dainty without being sheer* Strong pink flashWhat I didn't like:* Can't be worn as a top coat easily.Dupes: Closest thing I have to it is CG's "Temptation Carnation", which is sheerer (definitely needs three coats) and has little silver glitter in it.Would I buy it again? Absolutely. It's easily one of the best delicate white polishes out there.Would I recommend it? If you're looking for a white/pink metallic polish that actually builds to opaque, "Rainbow" is your new best friend.
