Aqueous Hobby paint can be diluted with water if desired, while paint brushes can be cleaned and washed out in water. Ensuring that this is before the paint is dry. In particular, the gloss level achieved with the use of Aqueous Hobby Colour gloss paints is excellent. Gloss levels obtained using gloss coat Aqueous Hobby Colours can be adjusted by using H-40 Flat Base - mix approximately 5% of H-40 Flat Base to convert gloss colours to a matt finish, or 5 to 10% for a semi gloss finish. The percentage of Flat Base used can be adjusted to vary the amount of gloss level obtained.
