Looking for something like a small, self-adhesive gurney flap to clean up flow on the sides.
I will have to work on a picture to show this better.
G'day 65whitelion.
In regards to air separation edges at the rear corners, I'd try some adhesive weather strip (with a triangular section) as an inexpensive trial.
I've bought some at Bunnings in the past.
