Find a color you like in Ultracote and your problems will go away, too. 25 years ago, I started using Monokote and was very happy with it. I've been very unhappy with the results I've gotten for the past several years now, and have switched completely to Ultracote. IMO, Monokote doesn't stick very well to balsa, almost not at all to ply, and doesn't shrink worth a darn. It also relaxes after being applied, and the resulting sags are almost impossible to shrink out.
