I followed all instructions for use including shaking gel polish vigorously for over a minute before applying. Only used OPI gel. It would take several minutes for each layer to become tacky, no matter what color. I painted thin layers. I used OPI Bond Aid, OPI lint-free wipes, the N99, the whole shebang. Sometimes my color lasted 3 days before chipping, sometimes 2 weeks. I just found the product didn't deliver every time.
I also have the CND lamp and several colors of CND shellac. That system seems to work much better. Color lasts longer and is more durable.
