In preparation for painting (originally planned for this summer, however recent events have delayed that indefinitely), I needed to smooth down the weave and remove the pinholes from the cowl. I chose to do the upper cowl first (the lower cowl was done later, in November). My plan was to squeegee epoxy over the cowl's surface, sand it down smooth and apply a high build primer.
First, to give the epoxy some "tooth", I sanded the weave areas with 220-grit.
Here it is after sanding it down smooth.When I went to sand it down, it became clear to me that I needed to
bring the upper cowl home and work on it in a more accessible location. Turns out, I could fit the upper cowl in my car's little trunk.
Once at home, I could work on it more easily. Here's the upper cowl after sanding the entire surface, getting ready for two, back-to-back, applications of epoxy.

All done.
