[ARC5] MEK, benzene, acetone for Q dope.

[Leslie Smith]

  An observation, but without actual experience.

  MEK is prone to rust ferric metals.
  I wouldn't breathe fumes from MEK (but I don't think any sensible
  person would do that).
  Benzene is a known carcinogen, but not liable to rust metal.
  Acetone should dissolve polystyrene "chips" but less hazardous than
  the other two.
