Bill,
I can't speak to the literature you have, except to say that I don't
understand it. No more dichromate is added after the oil painting begins,
so logic would seem to suggest that it would be a good idea to clear and be
done with it!
I'm also confused about the non-wetting of the print. Gumoil, like Bromoil,
exploits the fact that water resists oil. I haven't tried it, but it would
seem that if oil paint were to be applied to a dry print, that the result
would be a painted piece of paper! I guess you have a method of removing
the paint from the gummed areas? In any event, the highlights of a gumoil
are the regions of the print where the gum is thickest, and where there is
less-to-no paint present. One approach to might be to place the finished
print in a solution of Clorox (after the oil paint has dried!). This will
dissolve the hardened gum, and send it down the drain with the dichromate
stain.
As for "doing something wrong", well, plenty of successful gum printers DO
use dichromate-clearing agents, so I wouldn't sweat it.

Keith,
I can now see how my post may have confused you; sorry about that. You
are correct in the steps you outline and that it is probably closer to
bromoil than traditional gum printing. However, in the literature I
have, the step about whetting the paper before applying the oil paint is
not indicated; so that one is new to me.

Are they actually still yellow/orange even after you have applied

Yes, the gum image is still yellowish when I apply the oil paint. And
this is one of the reasons I am having a hard time getting clean
highlights. The literature I have states to clear (as an option) after
all paint has been applied. The fact that people on this list say they
never clear a gum image, or don't need to, tells me I am still doing
something wrong.
Bill-
