I have taped pinstriping on flames but for pin striped designs I would think that would be tougher??? I do know if you practice with the ol' mack sword and a video it comes along pretty well.
On flames after taping off the negative space I spray the pinstripe color first, tape off the inside of the positive space with 1/8" pinstriping tape which becomes your pinstripe, after that is done I back tape over the 1/8" with 1/4" tape to make a bridge to seal out any overspray, then the flames are painted, after thats all done I use a intercoat clear to seal the flames and pull tape, touchup then clear coat everything, in a nutshell I guess, that same technique can be used on scallops but on free hand pinstripe designs I am not sure how you would do it? The one benifit to a sprayed pinstripe is you can use a metallic that can't be pulled with a sword'.
I am no expert but have practiced a lot as well as done a car after a lot of practice & patience. I enjoy the fact of painting & finish work as after everybody asks if I built my car the next question always is, "Who painted it" and besides most body & rod shops get 50 + bucks per hour, something I enjoy thinking about even if it takes me 3 times as long. Heres my latest attempt.
