Short Description:  Step 3 + 4

Since it didn't work for me at the side I didn't even try on the top. But for the alternative method I really reccommend to do it with two persons. Luckily, my son helped. We just wetted the surface, and put the dry ply #1 in place. Stipulated this layer already with a cut off brush (cut off to 7/8" worked great), and remember not to pull the cloth but push it into position right towards the electrician's tape.
Then, layer #2 and #3 followed as instructed. Thereafter, my technical advisor recommended using prefabicated fibre glas strips from amazon. I only found 6 oz/ sq feet, i.e. 2/3 the recommended cloth weigth. In the end, this only meant I needed more layers to reach the desired 2" radius curvature. Also I decided to "fly" into the detent alternating from both sides instead of just stacking the layers on top of each other. This worked out great, to get a very nice and smooth curve. Also, since the KAI do not say anything about how long the filling layers are supposed to be, I decided to fabricate them to reach down to fill the detents by the side skins, i.e. 2-3 inch longer than the underlying 2"+ wide layers.
Continued the steep front angle with three layers as per KAI and closed everything with layers 12 and 13 (although these now are technically layers 15-16). For todays work I am quite happy and curious how tomorrows cover ply sheet removal will go.
