Thanks for the good tips. Shell was originally dark blue. I didn't paint yellow over blue. I did prime the entire shell white, then masked off the area to be yellow and painted the blue. Then masked the blue and painted the yellow. The tape pulled off both the paint and primer. I gave the shell a very light scuffing with 1000 grit as I didn't want to lose any detail. You can still see the two "V" stripes under the yellow. I'm using an old Paasche brush with air reduced to 20psi out of a 5gal pancake compressor. . It did seem that the consistency kept changing as I sprayed and would sometimes be down to nothing but air coming out. Had to keep readjusting.
I must also hang my head low (very low) for my tape peeling technique. I never thought there would be a right and wrong way to peel.
