Good explanation. I would add that peelply is quite inexpensive and would be a good substitute for your perforated electrical tape, and meant for the function you describe. But, the etape solution sounds like it works fine.
how do you get the peel-ply to compress the wetted out carbon? The electrical tape will stick to itself and leave a good bit of compression on the repair resulting in minimal sanding for a smoothish finish. It will still have a bulge where the repair is - but it's in one piece and a whole lot cheaper than a new stick.
