The sediment was collected at Operation Scarlift Site 49 (the "Sterling" Discharge) in Bear Valley near Shamokin PA. The loose floc was scooped from coated rocks into a five gallon bucket, dried at 40 degrees C, then screened.
The dry pigment was added to "basemaker" or clear-coat, the paint shaken, then screened through knee-high hose. Tim and Ron at Orrelli Supply in Shamokin Dam, PA, were very patient to allow me to do initial mixing experiments at the store. Back in the lab, pint-container-by-pint-container, the paint was placed into an ultrasonic cleaning bath for an hour, then mixed together. The ultrasound treatment was necessary to separate small iron hydroxide particles that tend to stick together. The resulting paint was more akin to a stain, being fairly transparent and having fairly low “hiding power,” hence the need for more coats than usual. It behaved much like what the pigment industry refers to as a “transparent iron oxide.”
At Tripplett Auto Sales in Boomer, NC, Von and Howard did the actual prep work and painting. A "reducer" (thinner) was added and the prepared vehicle was sprayed with about 8 coats of the paint, then 2 coats of clear coat. It was buffed after it dried.
Anyone wishing to try this approach should handle the basemaker in a hood at all times. The vapor pressure is quite high and the fumes are rather noxious.
This decal design is a collaborative effort with Nancy Cleaver, of Pensylvania Calligraphy (yes, it's only one 'n') Lewisburg PA 570-524-2880. The decal was produced by Middle Creek Signs of Beaver Springs, PA .
