Info & Guides
Corona Brushes: Made in the USA and Engineered for Excellence

For over 80 years Corona Brushes, Inc., has created the ultimate in painting tools. Their unique formulations of the finest quality materials provide the right amount of suppleness and flex ideal for application of marine coatings.

Ideally, you may want to have separate brushes for varnish and for oil-based enamel. For convenience when varnishing in warmer weather, keep a couple of extra brushes in each size handy so when one starts to drag a little you can replace it with a fresh one and keep going
