If you don't have time to buff your nails, you could do with a product that will give you the same results in 2 minutes. For me, it is Colorbar Nail Treatment.
Colorbar Nail Treatment can be used alone or as a nail polish base. I have only used it alone. I apply 2 coats and my nails look so much better, as if they are laminated. I really like the consistency of this product because it is neither runny nor thick. It is just right to apply evenly without any streaks. Hmm...I should use it as a base too.
