I painted an accent wall a few days ago and when I took off the painters tape the edge between the wall and the ceiling left a heavy thick line and the transition looks so bad. I know I applied the paint too thick so how do I soften up

I had problems with the Benjamin Moore paint also. I started out in my hall using the regal pearl (rec. by paint store). I had nothing but roller streaks. Second coat I tried to use more paint, it was worse then the first coat. Back to the paint store, complained,

I used Kilz interior oil based primer and my cut-in borders are noticeably lighter than the rolled areas. I only cut-in small sections at a time so I could paint the walls while the cut-in was damp. Should I cut-in again with the Kilz before applying the semi-gloss latex paint
