I paint clay pots regularly to as a hobby and to sell. I have found that the Patio Paint brand works wonderful! It's weatherproof so you don't need an extra sealer, though I do use their Clear Coat to give the pot a glossy finish. If I use any other brand of paint that's not outdoor specific, I seal it with the Patio Paint clear coat as well, and I haven't had any problems with chipping, bubbling or complaints either. Let's HOPE it stays that way!!:) Hope I helped some!:)
