After using Angelus Leather Acrylic Paint, apply Angelus Acrylic Finisher to your custom sneakers to help protect the paint from minor scratches/scrapes. Duller may be added to each finisher for a more matte shine. We do not recommend adding more than 0.5 oz of duller to a 4 oz. bottle of finisher. If using matte, make sure to shake the bottle very well before use.
