Default Best canopy method poll

I'm seeing a lot of stories about cracked canopies and as I'm about to decide which route, it would be really helpful to anyone at this point to get a better idea of the best way to install a long lasting crack resistant canopy.

Please note how long your crack free canopy has been in service. Thanks

I did this poll a long, long time ago. It asks a different question than you, aiming more at when one is likely to get a crack vs. what method will reduce that likelihood. What I found though was that if you make it through the build without cracking, your likelihood of having a crack goes way, way down. Also, this was before the period in which sikaflex was being widely used, suggesting that Van's recommended method works pretty well.

Long and short, I wouldn't stress about it too much.

Thanks guys. And the best summary / source so far is here: http://www.matronics.com/wiki/index....ng_Your_Canopy
Thanks to Rob Prior for compiling all that info!
I think I'm getting a better handle on the basics now.
