Today we continue with the finish after drying overnight you will immediately notice where you need to add pigments, here I have added the middle tone and dark pigments for a better color contrast. Don't forget that you always put pigments on a matte surface. I also use a product from Ammo (Moist Ground) which is diluted with thinner and only used at the top. In this way you get nicer color transitions. Dry this with a hair dryer, then we will use oil paint (Engine Grease) to my opinion one of the best products to imitate oil or petrol, in the photo I have already done a session and build further until I am satisfied myself ....
