Is it possible to limit the damage from Masking Fluid to brushes?
Although some artists swear by vaseline, soap or petrol, our tests do not show any of these methods to be 100% reliable or safe. The masking fluid should be as fresh as possible and washed from the brush with soap within a split second of use. Use low priced brushes or old ones if possible. If fine lines are required, a goose quill is ideal or for larger areas, a Colour shaper is excellent. The masking fluid can be rubbed from both of these.
