3 coats but 2 is fine. Heck, one would do if you were careful. This is the 3rd day of wear.
I never met a Nubar I didn't love. I'd show you all my Nubar polishes but I've sorted *snorts* by colour not brand so I can't. I got this from the guys below. Prices include P&P and this was on the Sale page. It isn't now (sorry). I'd say this deserves to be a cult classic.
