The gap between bubble and window sections of the canopy is just under 1/8". Van's calls out a 1/32" gap here, but some people have had trouble with thernal expansion locking them in on hot days. After you make the big cut, the two pieces sit differently, so getting these edges to line up again takes some patience with the sanding and scraping. The black Sika primer underneath the plexiglass makes a nice black targa strip on the canopy.
