Zinsser B-I-N Shellac-Base Primer-Sealer.
Great coverage! The room is going to look much better. And the fumes, oh w-o-w ….
I used to run a paint hood for auto parts back in the day; this stuff packs a punch about like that.
And how refreshing to clean up with organic solvents! Just like my father; brushes kept in gasoline…
So thanks, Bringiton. You were right on the money.
