The Mr Hobby Mr Masking Sol R 20ml from the modelling accessories range provides a superb quality masking fluid. Mr Masking Sol R contains a new formulation which can be readily applied, cut, and removed after use. This product has the same characteristics as the previous Mr Masking Sol M131, which is no longer manufactured. It is a water-soluble product, so when it thickens during usage, you can thin it out with tap water for extended use. Evenly apply Masking Sol R where you need it with a brush. Once it dries after 20 to 30 minutes, it becomes a translucent film. Cut unnecessary parts away, leaving masked parts, and then apply paint. When the paint has dried completely, peel off the Masking Sol R film. Masking Sol R is water soluble, so wash out brushes with water. Manufacturer: Mr HobbyModel: M133 Mr Masking Sol R 20ml
