Put a tape line of 2 layers of electrical tape on the skin about 1.5" from the joint. Sanded the skin and cabin top. Put on paper to protect the skin.
Glassed with 3" wide and a 2" tape around the back skin/cabin juncture up to the electrical tape.
Glassed the side joint, after filling the skin/top joint with micro, with black epoxy in the window area where the glass is part of the window frame and regular epoxy behind it. Glassed the windshield/cabin top joint with 2" and 1" tape and black epoxy.
Still need to do the door sill and edge joint, don't think I will use glass on it, just fill with flox.
