Even with the body off he won't be able to spray enough paint through
the holes at the end of `79 CJ-5 frame to get enough coverage to
preserve it. Got one, been there. He will be able to get a _bit_
better access if he cuts off the rear frame member/bumper, which will
allow him to spray paint a foot or so into the frame or about to the
trailing end of the rear wheel arch. But it occurs to me that all he'll
accomplish is getting a nice coat of paint on the piles of rust and dirt
back there inside the box.

The best solution is also the most expensive. That is to find a
place that will dip your frame. One dip strips off all rust and
the other coats inside and outside with rustproofing. They usually
also have powdercoating or paint options.

One option I have seen for the DIY job is to drill holes in the
side of the frame every couple of feet then spray in rust converter
and plug with rubber plugs. Not sure I'd recommend that.

Can you run a piece of flexible hose through there, say an air hose? Run
the hose all the way through, then slowly withdraw it, blowing air the whole
time. OK, now this is the good part. Spray paint in there with an
undercoating nozzle, while a helper applies a shop vacuum nozzle to the
other end!
