What paints will my Trade 20/Trade 4+ work with?

The Trade 20 and Trade 4+ are designed to be used with all conventional oil based paints and varnishes (i.e. all paints and varnishes which normally require brushes to be cleaned in white spirit/turps substitute). The Trade 20 and Trade 4+ do NOT work with water based or acetone based paints (introducing water or water based paints into your Trade 20 or Trade 4+ can cause irreversible damage).
