Also use for floral, figure and pictorial coloring. Directions for use: For use on natural veg-tanned tooling leathers. Be sure leather surface is as clean as possible. Apply with an artist brush, wool dauber, air brush or aerosol sprayer. Thin with water. Allow project to dry completely. Buff with a clean scrap of sheep wool or soft cloth to remove excess surface pigment before applying finish. Repeat until desired hue is achieved. Seal with a top finish coat. All Tandy Leather finishes are compatible with this product. Clean up with soap and water. Do not use on suede.NOTE: Some finishes will pick up a small amount of color from water based dyes. To guard against unsightly smears on background dyed projects, multi-colored figure or pictorial carved projects, apply finish on dyed area with a brush first to lock-in colors before applying final overall coat with a sponge or soft cloth.
