I\'m sure \"fleshy\" wasn\'t the goal as the coating had no real \"body\" to it.
If you squeezed the item and another \"uncoated\" item, you\'d feel no
difference.
It *may* have imparted a texture (rough vs. smooth). Or, it may have been
for visual characteristics (matte vs. glossy).
E.g., I have found a similar substance on the logo for some of my GPUs.
No thickness to it. And, I don\'t see how it would add much value in
terms of \"feel\" -- do you often stroke your PCI cards?
I\'m looking at relatively long service lives -- a decade or more.
So, wonder what the goal of applying these \"coatings\" may have been.
Were they trying to make an otherwise smooth surface appear to have
some slight texture (in which case, why not just texture the mold
and have that texture baked into the plastic?)? Or, was it a
visual issue just to take the sheen off of a smooth, glossy part?
(again, why not texture the mold and save the step of having to
apply a coating?)
*Or*, will I discover some other consequence of having removed the
coating that isn\'t as easily addressed with, for example, a textured
mold?

With a LITTLE elbow grease and alcohol, I am able to remove the

But with some items, may recur.
I \"cleaned\" a mouse with such a coating -- by removing the coating!
Now, the mouse has a *glossy* plastic finish instead of a *matte* one.
I\'d be hard pressed to identify which had the coating (prior to the
stickiness phase) and which didn\'t, based solely on feel.
I don\'t expect to ever need to \"clean\" it again.
If you have removed the offending surface layer then that is probably the case.
Most things that have this stuff on usually have an MTBF that is broadly
comparable with the failure of the soft rubbery plastics.

IMO, the manufacturer could have textured his molds to give a similar
appearance/feel to the mouse without the \"risk\" of this silly coating.
Or, the recurring cost for the material applied.
That sort of soft fleshy feel was in for a while. Manufacturers adopted it
without worrying about the cheap plasticisers allowing polymer degradation on a
~5-10 year timescale depending on ozone levels.

Most kit is replaced on a shorter timescale and so it is non-problem.
