Just wanted to echo my comments on Sika with a tip up canopy. I used garden hose washers as spacers, which are about .125" thick. This is less than Sika says, but it's an experiment (al). Both the windscreen and the rear plexi were attached this way. Not a single hole was drilled. 200 hours and 2 summers in Phoenix without any issues. If the expansion works in Phoenix - it will work anywhere.

Carl,
The sika flex is strong stuff. I did bolt the sides of the
canopy to the square rail. Maybe I was a bit chicken. But I used about
3/8" gap for the adhesive. You need space to allow for the expansion of
the plexi in the heat. The gap on the back is much less around 1/4" or
so. The windshield was no problem. Just remember that you need to cut
the bottom of the plexi after you space the canopy upward to allow for
the glue spacing. I had to remake the side skirts because I forgot about
that. THe fiberglass that you put around the bottomof the windshield
keep things in place. Plus you put the fiberglass "ring" around the top
to cover the gap between the rear and front canopy. I think it will be
there for a long.time. Fun priject that added about 6 weeks total to the
job. But then I have only a few bolt holes on the square tube.
