Why would you want to? Lacquer sanding sealer which is available at woodworking shops does a much better job of filling grain and does not shrink as much. The primary advantage of butyrate is that it resists the chemicals in model airplane fuel which is not an issue here. I use Behlen's in a spray can. It is high solids, dries quickly, and sands easily. I use automotive lacquers over that starting with a sandable, spot-filling primer which will highlight and fill any grain that I might have missed with the sanding sealer. Virtually anything will work over that once it has dried.
