I find using the sponge supplied means I apply a lot (too much) of the powder, and end up with a very mirror-like effect, which is not what I wanted. My second attempt, pictured, shows one nail using the sponge, one nail with no chrome, and 2 nails where I tried to wipe some of the powder off with a lint free wipe and acetone and it ended up a pretty colour, but very patchy. The colour coat is Call Me Maybe. Keen to try again using a spare polish brush as suggested in a review below, as I think this powder has a lot of potential, and I love the glazed donut look.
