No surprise
When I first read the post, I was going to be very surprised if anybody responded with a failure. I did as much research as I could find to dig up a Sika failure. It is mainly used for boat windows too -- I found none.
After having used it now, it is absolutely bullet proof and excellent stuff. There have been some previous posts here where guys have tried to have it seperate from the canopy (with hammers, pliers, smashing, etc), and all the results have been outstanding.
Might be a good idea if we can convince Dan (you know which one I mean) to pull out his test equipment (torches, flame throwers, jack hammers, etc)and go to town and let us know the results. Easy for me to suggest without doing any of the work. C-mon Dan, please? Dave
