hour or 2 thats the average. are you picking up something like i got posted up top or mineral spirits? cause mineral spirits wont work dont know about enamel thinner it has to be the acrylic enamel kind.
i just use this exclusively for painting.
the cobalt was a basecoat for the nailpolish since its semi transparent, the reducer is for the nailpolish.
i got some of that wally world stuff but havent been bothered to try it out yet
