How long will the fluid last in my Trade 20?

This depends on a number of factors (see “How do I minimise fluid consumption in my Trade 20?”). Typically a Trade 20 will consume about 2 – 3 ml of Brush Mate Fluid per day, so you may expect to replace the bottle of Brush Mate Fluid every 3 – 4 months. However, in some circumstances (e.g. if you store your Trade 20 in a van where there are large temperature fluctuations) consumption can be greater. Different paints and usage of your Brush Mate product may affect efficiency, make sure to check your brushes regularly.
