After receiving approval from TAF and double checking with other builders it was time to install the custom made channel cover.
Because the 2 side channel skins are not identical I needed a jig to know where to drill and cut.
Next I removed the flanges and the trimmed the pieces so that they become identical.
This was easy with the snips, Dremel, file, sandpaper and Skotch Brite.
A bit more smoothening is requires and also a bit of touch up with the epoxy primer.
