That's good to know, Jack, thanks.... however --
1. This may sound arrogant, but sobeit: I wouldn't trust any tests like
that unless I made them myself, and possibly not even then.
2. I myself got so sensitive to *turpentine* that when I sat for about a
half hour on a chair a friend who was painting with turpentine sat in 5
hours earlier I woke up that night with the giant hives I'd been getting
when I was still painting with turpentine -- before the allergy was
diagnosed.
By extreme care (and I mean VERY) I've been able to use dichromate for
many years, but...
3. Some people are even more substance sensitive than I've been. And
chrome is considered (according to medical faculty at University of Basel
and the textbook, whatever it was) one of the two most allergenic
substances to humans, the other being turpentine. They say that EVERYONE
becomes allergic to them in time.
Why tempt fate?
4. Not to mention the mess of a sprayer, the waste and cleaning. Trust me,
application with a 45 cent foam pad is easy & FINE !
Plus,
5. If I were trying to make something mechanically perfect, like, say a
C-print, I'd do.... um, C-print? (Yeccch!)
