Enamel paints are oil-based and give a consistent covering which holds the colour well. They take a little longer to dry than acrylics but will give a nice hard coat finish without any sign of brush strokes once they have been given adequate time to dry. They can be applied directly without the need for a primer making them easier to use than acrylics. They are also easier to remove if needed. We have a range of enamel paints to suit many different painting needs. A brand which has been popular with model builders for decades is Humbrol.
