Shoe....
Debra,
I use exterior house paint and acrylics. The patio paint and Delta Ceram coat paint are my favorites. I seal with Krylon Clear Spray but am experimenting with others. My clients who have them under the patio say theirs look brand new. One client put hers in the garden and with the AZ sun, it's peeling. She's a friend and I am doing it over for her.
Sadly, I never painted one for myself!
