Hello everyone on the planet. I m an oil painter using oils over acrylics but i always liked the matt finish and drying speed of acrylics. So lately i ve been trying to paint completely with this medium. I used to work with a mix of andrea and vallejo acrylics wich seemed to give me the right results. But recently run out so i ve purchased the new formula based andrea colours and i ve noticed that they tend to be a bit more glossy than the original ones that where dead matt, more like vallejo colours. So now i m back where i begun with the oils. No matter what medium i use a get a bit shine at the end of the painting especially with dark colors.This is good when i m treating leather parts but not so when i m painting clothes. So my question is, is there a brand of acrylics or a medium to mix with vallejo to make them dead matt?
