spray painted bottle caps, paint a tray white, arrange dry caps on dried tray, next used "acrylic water" to pour over the caps. Follow the directions, mix the compounds and pour it on. It's self-leveling, which is great! The tough part is waiting 48 hours, because it cannot be disturbed at all! The acrylic hardens without incident & is ready for use! #Soo doing this, my favorite kitchen colors and finally a use for all those bottle caps I've been saving for years!
