More custom touches on the canopy. I created a thin metal skirt to round out the corners of the canopy. I was hoping to make a more streamlined look rather than the angular look of the normal canopy. Also, rubber standoffs make fitting the canopy bow to the bubble a whole lot easier. Lastly, a great tool for trimming to plastic is called a "belt file". Harbor Freight sells them for about $20.
