Jon has used water-based paints for decades. Acrylic paint and its modifiers and gels are extensive in the market place. Although Jon uses many brands, he particularly enjoys Golden paints and would highly recommend anyone wanting to understand the vast array of products and techniques to take advantage of Golden's excellent website and great knowledge base.  The company was founded by artists and continues to serve the artistic community with new product lines, custom products and on-going on-line help.
