Scalecoat sanding sealer question

[Steamtrains]

Mark...I use the same matte clear finish spray that I use to finish a model after painting. Apply a light coat and let it dry thoroughly, then lightly sand it with a very fine emery sandpaper, and you're all set. I'll generally use a paint brush for this application, and an airbrush for the final paint coat.

You might want to do a "test run" on some scrap wood and see how it turns out... Good luck..!!
