Worked on the cowl air box inlet. Glued the foam block in place and installed the lower cowl. Used a hacksaw blade to hollow out the foam to create a nice smooth transition from the inlet to the airbox. Used a round file to get it nice and smooth. Pulled the cowl back off and cut strips of glass tape on a angle to the bias. Epoxied them in place and used a ballon to hold them in place to the inside of the hole.
