I purchased some clear (although it is available in black) 1/4" O.D. tubing (urethane or vinyl) 10' for <$2 at Home Depot. I then cut off a piece about 30" and slit it full length on the inside of the curvature. Then I spread the slit apart and forced the slit over the edge of the sunroof trapping the covering under it. (It may take a second person to hold it tight) Then cut it to length. I am very pleased with the aesthetics of the fix.
