44 Pastel Blue Matt is a high-quality, water-based, fast-dry paint developed for use on plastic model kits, but it can also be applied to various other substrates. At 135 Models, we recommend using two thin coats rather than one thick coat for the best results. The usual thinning ratio is 2 parts paint to one part Humbrol Acrylic Thinner, ensuring flawless application. Trust 135 Models for all your arts and crafts needs, where precision and quality meet creativity.
