I have never read so much rubbish about using oil paints ever . If you are new to this medium go to Metal models and use there colour mixes .
The secret to oils is less is more .keep away from additives ; use the paint pure , apply thinly and it will dry to a nice sheen which cant be surpassed .
as with all paints ; quality brushes are a must ,in fact acrylics destroy brushes quicker than any other paint
