Pettit Hi Build Brushing Undercoat

Pettit Undercoats are available in 2 varieties of topside paints for wood. Old Salem Yacht White 6165 is designed for application on wood above the waterline. A sealer should first be used on bare wood for water resistance and dry rot protection. On rough, painted wood requiring a smoother surface for the finish enamel, either of these undercoats will work well. These high-build products have excellent filling properties and can be applied in a full, one-coat application.

6149 Easypoxy White Undercoater should be used as a base coat whenever the surface to be painted is aged, cracked, checked, pitted, or in any way less than smooth. It can be applied to fiberglass, wood and previously painted surfaces. Easypoxy White Undercoater dries quickly and is easy to sand.
