followed the instructions above and got great results [SEP] i think part of it is choosing a good black under polish prior to adding the mirror powder as it needs that dark base to really shine and look like chrome i chose the dark blue to try first and it looked stunning when done the part i hate with gels is getting them off but i will work on getting better at that i love the tangerine chrome powder and will be trying that next these are gorgeous colors and i will be trying each of them in turn
