Water-Based Pinstriping Brushes series 70, by Andrew Mack Brush Company are made very similar to the Mack Brush Fast-Lite Pinstriping brush. The Water-Based Pinstriping Brushes series 70 has a mixture of Squirrel Hair & Taklon to give the brush more body. Latex or Water-based paint has a higher density and Mack had to mix taklon with pure squirrel for body & snap, but Mack kept a generous amount of pure squirrel in the brush to carry enought paint to make it a good striper. A great outdoor pinstriping brush for a windy day, holds it body and shape. Used by Pinstripers and Sign Painters everywhere! A generous amount of pure squirrel ensures the brush can carry enough paint to make it a good pinstriping brush. Available in sizes 00 (1-3/4"), 0 (1-13/16"), 1 (1-7/8") and 2 (2").
