I've struggled with nail color for years now. I've gotten 'bubbles' in them, or had problem with them drying. On a whim the other day I got some Opi nail polish when it was on sale and it's made a HUGE difference. No more of the cheap $1 polish for me, it made a huge difference. I just put on a thin coat, and no bubbles and it looked great!
I don't know if anyone else has the same problem as I've had, but the quality of the polish improves the rate of success greatly I think.
