Thanks for that info. I will experiment on some scraps of wood first before mixing the two. I used to paint sofubi for promotions, there was incident where the thinner was as if sizzling in the paint, caused a bunch of little bubbles. Ever since, I been cautious, reading labels and learned a little chemistry 101.
Thanks, I had a couple dog hairs in a layer and managed to sand the tiny line. I had to use a Qtip to fill it with poly then let it dry to sand it lightly again.
