here's the interesting part... it's not a fiber. The owner was telling me it's some material laid on like a cake frosting detail. I don't know how that's possible, when some wood slivers, cane, bamboo, or straw would work pretty well. This Packard happens to be the 1st one Phil Hill restored
I was surprised to see this Packard at the San Marino so long after seeing it at the LaJolla http://justacarguy.blogspot.com/2017/04/this-purple-packard-bucks-boring-paint.html because it belongs to the San Francisco Art Center car collection. I actually recognized it from the rims. I didn't remember the rest of the car, but the purple rims are cool, and stand out.
