There was a surprising amount of work and detail in the Mexican Coke bottle cap knobs.
Randy pointed out that the bottle caps would fit nicely on "speed knobs", one of several knob types available.
First, a couple of Coke bottle caps were masked off (to protect the paint on the outside).
Then Randy sandblasted away the sticky gum inside.
This texture would give the epoxy "tooth" to hold on when the bottle caps are glued to the speed knobs.
Randy then masked the insides and clear coated the cap's outsides with urethane...
