Recently, I've been using Acrylic paint on metal. Acrylic bonds well and dries quick. I'll be working with old coolers, tool boxes, ammo cans, hub caps and other scrap metal and antique hardware. I'm currently working with a 7.62mm ammo can. I'll most likely paint a pin up girl on one side, and we'll see what will adorn the other. I'll post more of these recent projects as I finish them, so be on the lookout!
