I had this negative experience with (El Greco) acrylic paints as described in my previous question How can I make my old acrylic paints dissolve and flow freely again? I tried once more to carefully mix my acrylic paints with water, I tried to do this with Amsterdam brand as well, but the results were miserable - I could not get flowing colors free, there were always lumps and clots and the water and the acrylic were not mixing well. I have heard about acrylic flow improver, but my local store offers only so called "mediums" for acrylic and the flow improvement is not mentioned as good properties for them.
So - now I am eager to try oil colors paints. There are specializes flax or popseed oils that are marketed as solvents and so - I hope that strong chemistry will make my oil pants into watercolor and tempera quality flowing paints.
So - is it reasonable to expect that oil paints technique will create more flowing and easy-to-work paints without lumps and clots than acrylic colors?
Especially I am looking to try van Gogh brand of oil paints together with popseed oil.
Or maybe I should user terpentine with oils, instead of popseed oil?
