I need expert advice--I am painting one side of acrylic sheet and then engraving the paint off on that side. Has worked perfictly and really looks good. Now when I attempt to paint the painted side that I have engraved with a contrasting color the paint crinkles, and ruins the sign. I am using Krylon platic shaker can on both. The company cannot explain other than saying the first coat needs to dry for 48 hrs. I told them it had dried for three weeks. Any advice?
Thanks
