Default 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?

yes on the translucent...
if you are worried...
mix some wood glue w/ water (1:1) and hand paint the plastic wood w/ the mix...

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

I'm not worried, but I am curious. Why does this routine work?

the plastic wood absorbed some of the primer or the primer didn't adhere really well because you sprayed... the glue mix is a premium sealer..

the kids used felt tips for their art work on the walls and trim..
primer/sealer/paint of several coats each and the art work is still bleeding through...
use the glue mix and and it will stop the bleed through in it's tracks...
MYB and Roy Drake like this.

This would have been the week that I'd have finished chewing thru the restraints...
If only new layers hadn't been added....

I'm going to use the mix you suggested. Out of curiosity, though, would spraying shellac on the wood first have helped?

Some of the wood fillers are very porous.The glue mix should seal them up. Some glues are very hard to sand though as they are somewhat rubbery so get it smooth while it's wet. I used to use the stuff that's thinned with toluene or laquer thinner.It's pretty crappy stuff. The best is Durham's. It's a dry powder that you mix with water. Once mixed you have maybe an hour to use it max. In many cases it dries harder than the wood you use it on.
