As I find old wooden children's chairs, I paint them and give to kids in my family. This was the last one I did for my Great Nephew. These little wood chairs are usually sitting in thrift shops all alone and sad.
Mine isn't really a tool but I LOVE the new glass paints from Martha Stewart. No more hand washing - hand painted glasses anymore! THese make them dishwasher safe, its quick drying , easy to cure and people love the fact that they no longer have to hand wash all the hand painted glasses. !!
I spray paint chairs before I do the detail acrylic painting on them. I do use a high gloss which I love but hate when it puddles. I will have to sand if I get heavy handed with the spray paint and get a puddle or drip. If I don't like the color, I just go over it with another but I do agree with the primer all in one.
