The new ducktail in place with the "belt" on the aerocap...
Yes, kach22i...those are fins on top.
I went back to Coroplast as my material of choice because it's easier to slide in/out than thin aluminum flashing. I think the Coroplast will be more resistant to air pressure than the flashing would have been.
Hopefully it will last fer the trip.
