It would be a bit like trying to fish a length of Romex up through a
wall without a fishtape, but yeah, it would work better than nothing.
I'd thought about those wands I hear that the rust proofing guys use to
spray inside body panel spaces. In the end I decided that my CJ would
probably never again see a salted, slushy road or not be parked in a
garage and did what I could and ignored the rest.

Over here in the UK we have big rust problems on old vehicles because
we use salt on the roads in winter (which are long and wet). We have a
product called 'Waxoyl' which is a thick grease like substance designed
to be sprayed into chassis members via access holes, you can get
presure spraying kits for it. It is fairly cheap (maybe $30 a gallon in
your money) and kills old rust and seems to work well (its horrible
stuff, based on white spirit). Not sure if its is available in the US
though, it is made by Hammerite. Maybe you could order it from here
over the web.
