I may be cheating but I lay some light grip tape (blue tape) over a heavy
grip tape. (ductape will work if you can't find anything else) Then remove
the top tape after the caulk has skinned over but the inside is still
slightly fluid. Surface tension pulls the roughness into a smooth bead.

I use Sis404, 5200, sikaflex 61a etc and blue tape off the hardware or
window surrounds and so on applying a moderate layer of ikumpucky with
maybe a 1/8 inch border and wiping off the excess. When I peel the
tape there is never a good line like with paint, it's always ragged or
smeared. I've tried different wait times but it's never much
different. Is there a technique you salty professionals use? Thank
you.
