@farmerman,
Thank you for the info. I have done some web research too. I wrote Winsor & Newton directly and they told me that you can use them together with regular oils. They act just like regular oils in texture and drying time, so there would be no separation. I have heard a lot of good feed back on them, but the two most common draw backs I have seen are
1. No one knows how permanent they are or if they can stand the test of time like traditional oils.
2. As they dry, it is not uncommon for the surface to have hundreds of tiny "holes" where the water evaporated out of the oil as it dried. This made the over all painting appear dull.
So I think I will use the colors I have and do a test painting and see how they do. I will use traditional oils and do another and just see what I like better.
