Before we talk about the different auto pinstriping methods we need to cover a couple of basic points :

1) Pinstripes are usually done in two colors: one that
compliments the body color, and another, thin line, which contrasts to
make the stripe stand out. There are no rules: color choice is a matter
of personal preference .... and imagination !!!

2) Make sure the surface to pinstripe is absolutely clean. Get rid of all residue with a good pre-surface preparation product

OK, now to the different auto pinstriping techniques :

Mechanical Pinstriping

A mechanical auto pinstriping is the best for striping long
areas like trucks, vans, or station wagons. The main advantage is that
it puts down stripes of consistent width, letting you concentrate more
on keeping the contour of the stripe aligned along your work surface.
The Buegler pinstriper and accessories are one of the preferred by body
shops and pinstripers for their high quality construction and
consistent operation. The easiest way to use a Buegler striper is to
set up your stripe line using a magnetic auto pinstriping strip. It
adheres firmly to steel surfaces, forms mild curves, and has a center
groove designed with the Buegler's guide arm in mind. The strip can
also act as a guide for your hand.

Striping with Stencil Tape

There are several different stencil tapes that are suitable for
almost any auto pinstriping application. Stencil tapes let you lay down
stripes of different colors without waiting for the other stripes to
dry.

Stencil tape striping requires brushes: the pinstriping brush is the most important element for an excellent final result.

Freehand Striping

This auto pinstriping method is the most advanced one and
requires the most practice to master, but offers unlimited flexibility.
The easiest method for the freehand striping novice is to lay down a
strip of masking tape about ¼ inch from where you would like the line
to be. Use the tape as a visual guide for your stripes. Do not use
standard masking tape for edging pinstripes. the pinstriping paint will
seep and bleed under the edge of standard masking tape. The pinstriping
can be as plain or as fancy as your patience and level of skill allows.

Regardless of the design, pinstriping is one of the best ways
to make your vehicle very unique. Like anything worth doing right,
practice will make worthwhile results .... and having the best possible
supplies is critical too.
