I'd fit the machine all together first. I have a two different cases
in which the powersupply goes in as a friction fit, and barely in at
that. Any addition to the outside of the ps would make it impossible
to fit in the case. Well, at least not with some dremeling.
That said, where as normal paint may add as little as a few
thousandths of an inch to a surface, this stuff will be quite a bit
thicker. Oh, 7 ten thousandths, approx it says:
Recommended Thickness: 0.070" (1.78 mm)
That's not chump-change to even loosely fitted parts, especially when
you factor in two sides, as appropriate to some components.
However, it should be much easier to just poke holes through it to
clear out through screwholes after the fact. Non-through screwholes
could be another issue.
Automotive supplies can come in handy for case modding. If you want
to recolor plastic parts (faceplates), look into vinyl-die. Works
