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?

Hi:

I ran into the same problem with Dow Corning 795 and Sikaflex 291. Two
considerations:

1) as another guy said, improve technique. Remove tape by: A) pull
directly up, B) pull tape from about a foot plus above the goo and 20
degrees into the bead, c) same as B only 20 degrees away from the bead.
Then try 45 degrees. See what happens

2) the stuff I use is much more manageable when tape is removed
IMMEDIATELY after application of goo. Letting the goo sit for even a
minute will increase the tack and get really stringy.

Like many other things........................ the more you do it the
easier it gets. Ever watch a pro do somehing? Makes it look oh so easy
and look so good when finished? Just takes 10 years five days a week.
