Primer versus Paint
Today I finished a utility shelf made with pine dimensional lumber. The bottom was screwed and glued to the sides. The screws were countersunk, and the screw holes were filled with Plastic Wood. For finish, I sprayed white primer.
The Plastic Wood-filled holes still show through the primer even though they are sanded perfectly smoothly. They are clearly visible even after two coats of primer. Is primer more translucent than paint? If I paint these, will the covered holes disappear?
