The recommendations by the National Windshield Repair Association are:

“In the acute area (an area approx. 8 12 x 11 directly in front of the driver), repair is recommended if the damage can be completely covered by a 25 cent US coin (.95 inch diameter circle (24.13 mm.), if the finished pit will be less than 3/16 of an inch (4.76 mm.) and there will be minimal cosmetic blemishes remaining in the damaged area after the repair is completed.”

Outside of the acute area the only recommendation is that the finished pit is no larger than 3/8 of an inch and the pit does not go as deep as the laminate.

With the Esprit you can repair any damage that will fit under a 50 cent piece, as long as other factors such as pit size and depth are not factors.
