For those considering Dr. Colorchip, I recently used the product on a relatively deep chip 1/4 x 1/16 of inch and 2 smaller chips. (which was actually a dent that was first removed). I applied several layers -- which is not shown on many of the videos I found on YouTube. I am also including a link of the review video I put together.
