The formula on Do Unto Others was really nice and it is well pigmented. I used one coat in these pictures, but would probably use 2 next time as there is still just a hint of visible nail line in bright light. Application was smooth and easy as well. My base coat consisted of 1 coat Seche Rebuild and 1 coat China Glaze Strong Adhesion base. I then topped everything off with 1 coat Manicure Extender. Sadly it was overcast when I wore this so I don't have any direct sun photos for you.
Do Unto Others really is a lovely rich teal. If you've never tried any Barielle polishes you should check them out. The Barielle website runs sales fairly often or you can find them at Ulta and other beauty supply locations.
