Repainting voyager logo badge

[damaltor]

Hi forum,
i am rebuilding an HP-15C from parts, more on that later. I have a logo badge, one of the newer plastic ones, which has lost quite some color over the years. is is already taken out of the calculator.
i would like to repaint it silver or white to make it pop out again. all my other voyagers are nice and shiny so this one has to shine, too. i might use white, because it looks similar enough and might be easier than finding "the correct" silver tone. also it could help in differentiating the device - it will be in everyday use next to a 16c.

My first try was to put modeling clay / play dough onto the logo and try to wipe it off while leaving it in the ridges, in the hope that i could then spray it with the can and remove the clay afterwards. the clay would not stay in the groves, or would cover up some of the elevated places too, so that was not a success.

any idea how to repaint this logo nicely?
