Using MinWax Sanding Sealer on balsa. I know I have used it before but lately I have been experiencing an aggravating occurence. The sealer is applied and left to cure at least a day but when I sand, it tends to flake off instead of sanding off. Almost like it is not penetrating into the grain. Anyone have any ideas about this? The balsa is not treated with anything prior to applying the sealer.
