The cowl is stock and not a fiberglass cowl. The joint of the cowl are carefully trued with sandpaper, and glue with thin CA. After that, a one-inch strip of cowl plastic material is layed over the joint to strengthen the cowl. Before the strip (1) is layed and glue with CA, the area is pecked with "thousands of pin-holes" with a pin (2) to ensure that the CA has a good grip on the strip. This extra work is all worth it.
