I have an idea that may be useful here, although, I haven't actually tried
it.

Use two pieces of guitar string to hold the razor blade edge parallel with
the cpu. Lay the string across the cpu and slide the razor along the
strings. This should enable you to get a thin, even layer (guitar string can
be as thin as 0.008").
