Removed clecoes holding left forward skin to stabilator and removed forward skin. Removed protective film from formward skin. Deburred left forward skin. Using a hammer I tapped out some very slight puckers where the forward skin was hitting the sharp edge of the forward ribs. Although I had already trimmed the forward ribs, they still needed to be trimmed a bit more. The bumps were not visible until I removed the protective film from the skin.
