Getting better! After I gave the whole thing a couple coats and went over the top with a thin coat of polycrylic. After that, I started to add a thin coat to the base, but noticed it was causing that dreaded RED stain to show through the paint in certain areas. So I stopped, waited for it to dry, lightly sanded and repainted. I'm going to let the paint cure naturally and forget about a topcoat.
See on the sides where the corner pieces meet the side? I later caulked these areas to make it nice and seamless.
