I recently picked up a bottle of Vallejo's chipping medium, and went to try my hand with it. After applying water and gentle abrasion with a brush, I didn't get the tiny chips I was looking for but rather most of the top coat just wants to come off in a big rubbery skin..

After experimenting with 1 or 2 layers of chipping medium, thinner coats of paint, and going and getting a bottle of Aqua Net hairspray, I've concluded that the problem seems to lie with using this chipping method with Vallejo paints... some googling seemed to confirm this but yet I see videos of people using Vallejo's medium and paints and it works great together. What am I missing?
