It's a great replacement for AeroGloss Balsa Fillercoat and Sanding Sealer.
I'm impressed! The first coat raises the grain a bit like the old AeroGloss Balsa Fillercoat; a few swipes of 220 sandpaper
and the part is smooth... Of course, depending upon the grain, 1 or more extra coats may be required. I plan to get more.
