Anthony, I did install the ply bands. I purchased a sheet of 1/32 ply, and cut and extra set of bands. I laid down two layers of the ply strips. The first layer (bottom layer) was 1/4" narrower Than the top.

The narrow band was glued flush to the rib. The top band was glued over it, with a 1/4" overhang.. This is plenty to hide the joint, and the extra layer allows the outside wing panel to slide on easily, without snagging that thin ply strip.

I glassed the strips with 1/2 oz cloth for durability.
