Invention of silicone

On repair job for customer's bike,, ,, this is the way the bike came in.,, so it has to leave the way it was,,

Chrome rear axle nut,,,

Then chrome stamped nut COVER,,,




Then another chrome stamped nut cover cover to match the size on the other size...


Tada,,,

These are glued on by silicone.
I just wonder if the scientist who invented silicone had any intension for this particular application..
