Well there is a lot of truth in that for sure! LOL
However, I do have to admit that the stuff I got does not resemble what is on the car in either shape, texture ir finish. It's a lot thicker and 'grainy' wheras the tapes on there just now are practically smooth, like black insulation tape.
I looked at them again with the trimming idea in mind but there is no pattern on the backing that would help do this and it look frikikin hard to cut or trim to the shape needed....especially where it narrows to just a few mm at the rear quarter panel.....
I give up!
