This weekend I built a Motrak Model Supply Shed using Crackle Medium for aging. I got this Hobby Lobby.This has the three step process: Base coat, crackle medium, and final/ top coat. The base coat of acrylic paint should be dry. Apply the crackle medium and let dry 1 hour. Apply top coat for an instant aging effect.
Sponged on base coat for additional aging.
