The joint got a coat of CWF and sanding.
Notice you can't see the U support piece, it's hidden inside the joint.
I wrapped a paper towel around the vanes previously painted with the metallic black.
I carefully sprayed some filler primer only on the joint.
After that dried, it was sanded with 400 grit on a block.
I was concerned about any misalignment of the joint but after sanding, the fit was good.
A glue fillet was applied to lock the U brace piece in place.
