I applied 1 coat of Avon's NAIL EXPERTS Smooth Beginnings Base Coat, 2 coats of Diamond and 1 coat of Avon's NAIL EXPERTS UV Gloss Guard Top Coat. Using Avon's base and top coat has helped my polish last at least 4 days with no chipping. That says a lot since I work with my hands daily (I hand craft jewelry for a living in case you didn't know). When I clean my house, I wear those handy rubber gloves to keep my skin from drying out but it really helps the polish last longer too.

It sucks that this stuff is discontinued!
