It's been a week since I posted that I would compare W-N's Griffin oil colors with other oil colors. I threw in some acrylic color too.
The paints I tested were;
Winsor-Newton acrylic
Winsor-Newton high cost oil paint
Winsor-Newton's Winton color - Student grade oil paint
Winsor-Newton's Griffin oil paint
Daler-Rowney - Student grade oil paint
I tested them on glass, stainless steel, chrome, aluminum, painted metal can, lacquer, polyurethane, and five different kinds of plastic.
Bottom line, the acrylic was the weakest in adhesion. Not by much, but when scratched hard, larger pieces came off. All the rest were the same with strong adhesion, but could be scratched if some force was used. Thin coats of Griffin dried overnight.
I did not have anything that I knew to be resin to test on. My judgment is that if oil paints will stick to something, Griffen oil paints will too.
Check the Griffen oil colors here. Be sure to scroll down and see the prices. You'll love the prices and the fast drying time.
