Upol "High 5" aerosol primer was used after I filled the seams. All the paint is PPG DBC urethane basecoat. I painted the entire cowl white first, them covered the cowl with masking tape. I drew the checkers on the tape and used an Exacto knife to cut the checkers out. I tried laying out the scheme with fine line tape but found I couldn't get the pattern very even looking - hence drawing and cutting. The black was sprayed next. I then masked the checkered portion and moved on to the red - masked that up and then sprayed the blue. Both the red and blue sections were un-masked leaving the checkers masked. I back taped the area that I wanted the silver stripe, sprayed that, unmasked everything and applied 2 coats of PPG DC3000 to the entire cowl. Being a sport plane I left it at that, no dirt and very glossy. I could have sanded and polished it but the GP cowl is a little on the shall I say fragile - flimsy side so I didn't want to tempt fate. Hope that helps you.
