Everyhting that Mark said below plus i did use West Systems and there is no sign of a problem from the start. I did use very heavey sand paper like 60 grit and made sure that it was fully toothed ( no glossy areas left at all). I think that I also drilled some holes through and let flox tie both sides of the lay up together. Also don't for get to tape it off very well so no epoxie gets on any part of the exposed windscreen. My canopy was from Rand but I can not imagine that the products differ as they are made the same way.Joe HortonCoopersburg, Pa.

I would think most epoxies would stick just fine to acrylic after it's been roughed up with rough sandpaper to give it some "teeth". I think this is even detailed in the Bengelis books. I suspect those having problems didn't do the roughing part. I wondered about the quality of that bond when I did mine the same way (overlapping the acrylic by about 1.5"-2" all the way around, but there is zero sign of delaminiation anywhere. T-88 may not be the best choice because it's not very viscous and may not soak into as many of the scratches, but I'd bet it's still a pretty good bonding agent for glass. I used Aeropoxy, and can tell you that it works for sure, at least up to 240 mph. Another key is HOW you do it...you need to sandwich the acrylic on both sides with glass to put it in a sort of "double shear" rather than glass on only one side, eliminating a "tension only" kind of failure where the fiberglass can just peel away from the acrylic due to some wierd loading condition. I think that's just good common sense though... ____________________________________________________________ Obama Urges Homeowners to Refinance If you owe under $729k you probably qualify for Obama's Refi Program http://thirdpartyoffers.juno.com/TGL3141/4d12543eeacb788c396st01duc
