I did not find a previous post on this subject, so I have a question. When you want a "soft edge" for primer, you flip the edge of the tape so the back side is stuck to itself about 1/4" on a 3/4" roll. Then when you spray to that tape line, you get a soft edge as long as you dont load it up under the rolled up edge. Is this correct? Im looking for an easier way than having to feather the edge of the primer edge after the tape is removed.
