Charcoal lighter is very similar to kerosene and some use it for starting fires on cooking grills.  (the air around O'Hare Airport in Chicago usually smells like a cook-out).  I think Zippo is more refined and expensive.  It is very likely that the residual oils that makes my starter less refined is the very stuff that stays in the paper and makes it translucent. 

You say that baby oil is absorbed instantly, but I bet it actually takes a second or two to really sink in. Rubbing oil on a large piece of paper takes some time.  Fluid bottle in one hand and squeegee in the other, I can treat a 12x19 inch negative in a couple of seconds - and there's no going back to cover missed spots.  I'm working with small negatives now, but my goal is to be soon using full-sized Masa sheets - or even bigger - so I need a faster process.

I see. Well, we used plain stationary paper in the Istanbul workshop and the
oil was permeating instantly - probably you're using a special inkjet paper.

Charcoal starting fluid? Seems like a nice solution - my compliments. Is it
something similar to Zippo lighter fuel? We don't have liquid starters here,
only dry ones...

That's a good idea - measure the print, print inkjet to size, repeat.  It
wouldn't matter if it DID keep shrinking.  But this Masa is too thin handle.
I really need to have it mounted.

It takes forever for the oil to permeate the paper and it contaminates
everything.  One has to be very careful where one places a negative or what
one touches.  But I found a solution: charcoal starting fluid.  Goes on very
fast, evaporates from wet to very dry in a few minutes.  No need for a mylar
or plastic-wrap barrier because the paper is translucent but not very oily.
And in an hour all traces have evaporated and  you can't tell it was ever
soaked - the paper reverts back to the original and so is easy to store.
