I was reluctant to get started on the cowling. For one I didnt want to sand any more fiberglass. Had enough of that mess. Secondly, I was worried it would be a long tedious road, like the doors were. Here are a few videos detailing my journey on the cowling. An aspect the videos dont detail that was important is we attached the bottom cowl to the plane and then laid the top on and temporarily clecoed the front center ring on the left and right sides of the center ring to hold the top and bottom together in a way that made the gaps fit ok. Then we were able to trim the back and sides of the top cowl.
