One way to keep your hand cut,45 deg, bias tapes neat and uniform
is to lay them up on clear poly (Home Depot plastic sheeting) then
after you get them worked to your best epoxy / glass ratio,
cut the assembly to your needed width & length and cary the layup
with the nonstretching poly backing , flip over and apply to the
joint.

Peal the backing off , finish and inspect.

While the tape may be more convenient, the extra thickness of the edge
sticks out. What I like to do is roll out a piece of plastic wrap,
roll a piece of peel ply on top, paint on a little resin, roll out the
bias tape, saturate with resin, roll out the narrower hemmed tape,
apply a light coat of resin in the corners, apply the whole works. You
can run your fingers against the plastic to insure good contact. Then
get a piece of foam rubber with a wood backing, press against the
plastic with weights, clamps, etc. to keep pressure on. The peel ply
will absorb excess resin and when cured and peeled off, the joint will
look great. Spray on some light grey primer and finish with spatter
paint.
