MAC Ming Blue + OPI Gold Digger

I layered Sephora OPI Gold Digger Topcoat over MAC's Ming Blue...I've noticed that the Gold Digger dries almost a bit matte, so it killed the sparkliness of Ming Blue...I had to add another layer of MAC's topcoat to make my manicure shiny again...but I really liked this manicure it reminded me of a sparkly night sky...it was subtle yet definitely stood out...just wish the OPI topcoat wasn't so mattifying...=(
