How about actively removing the heat: a gable-mounted exhaust fan, with
or without a thermostat control. Depending on the CFM, you'll need a
certain area of "inlet" into your shop of fresh air - got a screened
window?

The collateral benefit to the exhaust fan is it moves out the fine dust
too.

A gable fan and vent system would be nice, but it is a cinder block
building and the cinder blocks go all the way to the crown. Would a fan
really cut down much on the radiant heat?

It dropped the temperature in my old shop from scorching hot to
whatever temperature it was outside in a matter of minutes, and it
sounds like you have exactly the same situation in yours. IIRC, they
had some vent fans that mounted directly to the inside of the roof
right next to the ones mounted on the wall at the hardware store, so
that may be easier.
