A fresh coat of acrylic paint will be solluble by isorpopyl alcohol for many days after application, perhaps forever.
Instead of the hairspray chipping technique, which involves a lot of B.S., why not apply a base coat, followed by acrylic top coat, and then use painbrush dipped in alcohol to chip away at the acrylic top coat, exposing the base coat?
The base coat can be proofed against alcohol by using oils, lacquers or even Future floor sealant.
