Trim nose skin. Tried to use Homebuilt Help technique of cutting with blade -- I didn't have the right blade. This turned into a PITA because of the excess filing I had to do. When cut with shears, line was straighter in the end and much faster to file. Can't do each hole deburr on skins -- will take too long. Need to give in and do the flat file technique to knock burrs off. Can buff out minor scratches with Scotch-Brite. Still have to deburr skeleton ribs and spar and second side of rear skin.
