i do not see how it is better than no base coat [SEP] for me the color nail polish coat adheres to this fine why would not it but within a few days the base coat separates from the nail i am not sure what the advantage is versus using no base coat at allupdate june it might not be the products fault i learned that some people have naturally oily nails just like hair and skin can be oily and this would inhibit good adhesion i am supposed to de grease my nails with alcohol first and then base coats should adhere better when i get around to trying that i will post another update with my results
