RV9A, tip up
I used Sika exclusively for all my canopy bonding, with excellent results, including bonding the front of the canopy to the 702, as you asked. I detailed how it was done in my web pages, you can see it all by following this link. I did some tests with Sika, that are also in my web pages. It sands very well, but the sanded surface is kind of rough. I didn't leave it as the finished fairing surface. Turns out, fiberglass and epoxy adhere to the sanded Sika extremely well (I did some tests), so the normal layups over the front of the canopy to form your fairing are no problem at all. My plane isn't quite finished yet so I don't have it painted, but I did paint it with primer, etc. after all the finishing work. No issues whatsoever with cracking or anything. I love this material! Here's the link, and a picture of my finished canopy fairing. Just follow to the next page, and the next, to see all of my work:
