This was fitting the top of the boot cowl with a layer of foam tape, both across the front and along the edges where it meets the lower portion. This is where it became obvious that everything was going to be too bubbly to look good. I inquired to Tony D at factory and he clarified that they just use the foam tape on the rear edges against the fuselage tubes for sound deadening and to seal to the door better. Had to drill some rivets out of the lower sides and start over.
