I built a jig about a year ago,--mdf--that I need to modify (and it would be too time consuming to just build another one).
I used spray shellac on it (can, Zinnser dewaxed), and so need to remove the shellac in a half dozen places where I have to glue on the new modded pieces.
Each place measures about 2 inches square.
IS there a way to remove the shellac without sanding? Would alcohol or Acetone wipe down take it off?
I will sand it if I have to but would prefer not to.
