Roadster,
As a Pinstriper since the mid 50's I am curious about something. What kind of paint did your Airbrusher use and did it have to be Clear Coated?
Also did he scuff the area to be striped after taping it off prior to applying the paint?
I love the job he did. I understand the process as I also have been
Airbrushing since the 60's. I do the "hand-applied" stripes if the customer insists, but will always prefer to tape off the long lines for a straighter and more even-width stripe. Then I use a freehand brush to do the curves.
I don't often use the Airbrush for striping unless I'm using the Automotive paints which then have to be Cleared.
One of the neat tricks to taping off the area to be striped is to use One-Shot lettering Enamel. No Sanding or Scuffing the surface, just cleaning it good. THEN, after painting the stripe in, carefully remove the tape as soon as possible so the edges of the painted stripe can lay down. Thus, giving the painted stripe a soft shoulder, making it difficult to tell it had been taped off.
