Wheel Finish

In terms of the finish on wheels(black powder coat), full gloss or ~70% similar to the frame finish(?)
 
Real shiny powder is #60 gloss. There is a #80 but boy it costs $$'s.

As the dip paint looses it's pigments and the solvents flash off I'll bet 'the 1930 dip tank guru' had to continually run the Zahn Cup test on the tank. Ford ran very high speeds on the conveyors. Ford needed a paint that would flash off and be forced dried in a steam heated recirculating oven to keep up with the assembly line. You wanna bet it stunk on the line?

As the dipping paint became a little too thick then a splash of solvent was typically added until the correct number of seconds ticked off on the stopwatch waiting for the dip tank paint to finish running out of the #2 Zahn cup. So you may see some variation from car wheel to car wheel.
Want to kill gloss? Add solvent. Generally speaking.


I always ran about 22 seconds when painting 32,000 Herman-Miller rods a day with Mauwer-Shoemacker paint in my 280 deg electrostatic reciprocating 11" disk Randsburg loop dry filter down draft liquid booths.
Friction drive on the spinners used to hang 5 H-M rods per hook was 13 revolutions per 10 foot of travel in the booth on the 280 deg rolled the easy way 4" I-beam/458 chain overhead monorail conveyor, hangers on 8" centers with intermediate clevis at 15 fpm.

Then flash for three minutes and bake at 300 deg F. for 18 minutes, cool and off-load into wooden crates. First flatbed truck out at 7:30 am based on a ten hour day, 6 days a week. I had five guys on the line to load and off load. Four were inmates from Jackson Michigan State Prison at 75 cents an hour. The State made up the difference for minimum wage laws plus fed them, housed them, transported them, and gave them lunch. They were my best workers at Junction Mf'g. in Rives Junction, Michigan.

The grey waterbase PPG primer of the Hyundai Sonata as seen on the TV commercials is applied in an [E-Coat] electro deposition paint tank. Here is how these things work; based on this 1977 sketch I drew up while gabbing on the phone to a prospect.
First thing e-coated was the rocker panels of the 1960 [?] Ford Galaxy and it was done on Germany. Everycar made now is e-coated in primer. I had my 1959 A-H 100-6 e-coated after a molten salt bath stripping in Chicago.
