I'd had this broken Isis CLOCK clock knocking around forever, but was recently inspired to dig it out after noticing an Isis RADIO radio on Pat Albeck's cluttered studio shelves.

Thing is, after fitting a new movement, I figured the white plastic was so sun-yellowed that it might as well be actually-yellow!

Vinyl dye is perfect for plastics, it permeates the surface and is less prone to unsightly scratches... apart from where I dug my nail in to test if it was dry. It wasn't.
