Sanded cowl bonnet, trim tabs, and upper cowl with 400 grit sandpaper in preparation for Aerothane spraying. The cowl bonnet had already been sprayed in Aerothane. But I ended up with a couple of runs by the NACA air ducts. So I had to sand them out and repaint. I cleaned all parts with C-2210 solvent followed by a tack cloth. Then sprayed 3 cross coats of Aerothane.
