A base coat of Dermelect Makeover... I love how it makes your own nails look better, and removes a bit of the yellow tinge that they have at the moment. (This was sent to me for review)

Here it is with a coat of OPI Pink Before You Leap
With a coat of NYC Love Letters
and OPI And This Little Piggy...
I think this experiment was finally finished when I added Sally Hansen Hidden Treasure!
This experiment took place over 5 days... Instead of removing it I would just add another coat!
I think I had about 12-13 layers by the time I was done =P
