More pinholes! more filling, sanding, wash down for painting, then find more oinholes! Seriously getting bored with this now!
Eventually managed to get a coat of 2 pack epoxy primer on, and looked ok.
I removed the baffle seals and the cowling fits well without them... I decided that they were too stiff, so I'me going back to "Cowl-Saver' baffle seals. Hopefully they will be here in 2 days time.
