Yep, 2 of these at our field and I built both of them. Both have bad canopy's. The second one I fiberglassed the screw holes to prevent cracking. All this did was allow the canopy to crack around the glass. I think the only thing that "might' fix the problem is to glass the new canopy around the edges and use canopy glue and trim tape around the edges and toss the screw mounting system.
