Using a primer gives a good foundation to your paint: it smooths out any imperfections and fills open grains on wooden surfaces.
For slippery surfaces where sanding is not an option, Fusion Ultra Grip is a highly effective water-based bonding primer.
Fusion Brush Soap is a must-have for keeping both synthetic filament and natural bristle brushes clean and in tip-top condition, and can also be used to revive brushes with old dried paint in them.
