You can try this, its an old wood workers trick. Get a paper or plastic cup, cut or drill a 1/8 or 3/16" hole in the cup. Mix your paint, holding the cup at least a foot above another cup pour your paint into the cup with the hole. Depending on the thickness of your paint you may need to raise the cup with the hole higher. What you will be doing is called the bombs away technique. What is happening is when the paint goes through the hole it forces some of the bubbles to the surface. Then as the stream of paint leaves the cup through the hole you will see it getting thinner in between the cups. As the stream gets thinner it is forcing the bubbles in the paint out making them quite literally pop between cups. You will need to experiment with the hole size and the space between the cups, depending on the viscosity/thickness of your paint. You can also try thinning the paint which will help a lot.
