First off, I learned I need practice on applying stain.

Anywho...
I tested Minwax Wood Filler a 2 part filler with a added hardener.

And Lastly PL wood filler.

Being a beginner woodworker some of my joints on the trim were not exact..

The Elmer's look more like wood grain than the PL, but did crack when I put some pressure on the board.
Just thought I would pass this along.
