Out near the tip, I don't have an inch of surface area for the tape to stick to resulting in overhang that I want to trim off.

In my case, I'm only going to use Blenderm on the rudder which has more than an inch of surface area at the bottom and probably only 1/2 to 3/4" of surface area at the top, so that's where I'll have overhang to trim off.

I use monocote to seal the ailerons and elevators which I find much easier to work with and just as effective. My reason for using Blenderm on the rudder is because the painted surface on the fuse doesn't like the heat of an iron.
