PRO Acryl 1-Step is formulated to give you vibrant color in one single layer over a bright base coat. These colors also give you an initial contrast between the darker spots on the model and the brighter highlight areas without having to even think about it! Simply apply PRO Acryl 1-Step colors over a model primed either in a bright color like white or over a zenithal primed surface that uses a bright color over a darker color (white over black for example). 1-Step colors will give you more depth to the model than a simple, single layer of normal paint, but with the same easy application. No special tools or techniques necessary. PRO Acryl 1-Step colors can also be thinned or mixed with other PRO Acryl colors to give you limitless possibilities when doing more complex techniques or to extend your ability to find just the right combination of colors. A tool that grows as your capabilities do and is always ready to add more awesomeness to every project! 22ml per bottle
