To use MelPAX Thinner, simply mix it with MelPAX Colors at any ratio you like depending on the effect you want. For creating washes and glazes, add the thinner until you get a watercolor-like consistency. When using it with foam latex prosthetics or for tattoo cover-up, make sure to apply MelPAX evenly. Always remember to keep the thinner away from your eyes to avoid any irritation. Before each use, shake the bottle well to ensure proper mixing. Store the thinner in a cool, dry place. Do not try to use MelPAX Thinner and Airbrush Thinner interchangeably as they are designed for different purposes.
