Bottom's up. Mask, draw line where cut needed on tape. Cut thru 2 or 3 layers in the corners. I use a ball point, it rolls smooth on the tape. The residue ink from the pen is sticking to the tape, it will come off when alcohol is applied. Dust clear on the color lines, let dry few minutes, follow with color. Easy on the edges, do not let it flow, but keep consistency. Let this dry 8 hours, pull tape off. Best pull tape over itself. After dry, wet sand. I still am thinking of color separation stripes, 1/2", may just go with the red at the blue and blue at the red.
