Grey,especially maybe on nails is probably generally seen as quite boring, but I personally love quite monochrome or plain coloured nail polishes. I have wanted a nice grey colour for a while - I picked up this one from a make-up sale for $5. It's Rimmel's 60 Seconds Nail Polish in 803 Man Overboard. It claims to dry in less than 60 seconds and says it's a one coat nail polish. On the one hand, this nail varnish does try quite fast so not having to wait around for five minutes for my nails to dry is a bonus. On the other hand, I do think that you definitely need more than one coat. I like to think two coats is a good idea so the colour pay off is completely opaque. Because it dries fast, two coats is no biggie, and anyway, with any nail polish, I would do an extra coat.
This nail varnish is more a dark based grey rather than a blue based grey, so if you're after a pretty light grey, I'd look elsewhere, but these nails practically go with anything in my mind. So far I've had this on my nails for a good five or six days and there are no chips except for one which occurred the night I painted them (as I was at a party and clearly not caring much about the well being of my nails). I quite like Rimmel nail polishes; I've got another one lined up to try soon which is a pretty light blue - maybe I'll save it for a rainy day. Have you tried Rimmel nail polish or anything from this particular range?
