Weird enough YES! You can use Bondic to fix your fingernails by applying it in thin layers on your damaged nail. You can also work with a surplus and use a file to get the shape you want. Not only that, but you can polish and vanish it as well. Please be careful as the Bondic gets warms during the curing process. The tip is to harden Bondic on your fingernails by flashing the LED on and off to extend the set.
