Thanks for all the help Jerry & AmIGonnaFail. Had him use just the 40 vol. last night with swimmer's shampoo afterward and something else with propylene glycol. Tonight we'll mix powdered bleach in it so it will actually do something.

Great advice on shaving everything except the armpits - makes it a lot less grueling. If they say anything about it, he'll just say his wife doesn't like hairy guys.

And I'm planning on having him use TW, Zydot & Magnum shampoo the day of, just cause we're paranoid about this and have an awful lot riding on it. More than a job offer at stake here.

Will definitely post results.
