No top coat?: Fusion is formulated with a built in top coat, the 100% acrylic resin. You do not need to use a top coat for water permanency!
Tip: On a microscopic level, flat or matte finishes have tiny ridges and valleys when the paint dries. Therefore, finger prints and marking can occur. The marks can easily be removed using a damp cloth, however, if you are concerned about dust marks, apply a coat of FUSION Beeswax Finish or FUSION Tough Coat.
