I opted to use Cee Bailey windows when I ordered my finish kit. I have nothing to compare it to, but the overall fit of the Cee Bailey windshield was poor and required a lot of trimming.
The lower left edge of windshield (pilot side) came trimmed too aggressively at the lower left corner, requiring the aft edge of the windshield to be trimmed along the entire edge.
After hours of trimming, measurements, and trial and error, I finally got the windshield to fit reasonably well. The bottom edge had be slightly more aft than visually indicated in the plans.
I then proceeded with the window install, using the Silpruf method as I did with the side windows.
The Silpruf method worked really well, leaving a very clean finish line along the interior of the cabin.
