Does alodine contain chromium 6 --hexavalent chromium?  If so, be aware
that ch6 is a DNA mutagen; the FDA classifies it as a carcinagen
especially of the lungs and the gastrointestinal/intestinal tract. Check
this out on google. I did not persue finding out the ingredients of
alodine; but I recall hearing this more than a decade ago (after I had
alodined my pars!).Can anyone confirm that alodine does, or does not,
contain ch6?

John,
   Alodine does have Chromic Acid which causes cancer. I do not know
if that is the ch6 you are talking about. It probably is.  I wear an
organic vapor respirator andchemical gloves when handle AlumiPrep 33,
Alodine 1201 and The epoxy primer. Caustic, Carcinogenic and Toxic. I
will be even more careful next time. I have felt like hell the past
two days. Six hours in a respirator, it is bound to let some slip
through around the edges. The AlumiPrep foams and bubbles and produces
gas. The Aldoine probably does too if it works. I think mine was too
cold to work.
   Would you not use it again because of its Carcinogenic properties?
Would you just skip that step and use the acid etch and etching primer
only? Or some other process?
