Ah, I tried the makeshift dulcoat of three parts water to five parts rubbing alcohol to 2 parts elmer's white glue. I couldn't find rubbing alcohol, so I used the closest thing: purell hand sanitizer. The mixture goes on clear and when it dries it really reduces the scratching, but you have to put on at least two coats before it does so. When applied to apple barrel it almost has the non-scratching properties of tamiya paints! It works wonders and adding purell to the mixture instead of rubbing alcohol makes it smell really good!
