UltraCover Trade Vector Synthetic Filament Professional Paint Brush, is manufactured using a mixed blend of tapered and self-flagging synthetic filament. It has excellent performance in all solvent-based, but is exceptionally good in water-based paints and coatings. It offers good paint pick-up and release as well as holding its shape well. It is made with an unfinished beaver hardwood handle and a stainless-steel square ferrule which means it is resistant to corrosion - helping the longevity of the brush.
