Today I removed the primer from the problem areas of the canopy frame, which was basically the two front corners, a small area on the targa strip and along the "ear" of the right side. The primer came off fairly easy with Acetone. These areas were then lightly sanded, vaccumed, and Acetoned again before applying another layer of Rage filler.
