The tools and materials for pin striping are available from Eastwood
supply, who for years has supplied unique/specialty tools and materials
to the old car hobby.  They can be reached at 1-800-345-1178 or

They have roller pin striping kit with which even a ham-fisted idiot
(me?) can achieve excellent results.  I've used it for years to stripe
cars, music boxes,other antiques and anything else that gets in the way.

    ... and as they say "I have no financial interest in the company"
