I would like to bury my coax for a distance of about 20ft. The location
consist of 6" of crushed decorative rocks over the top of very rocky soil.

I intend to take the LMR-400 coax and push it through a garden hose to add
a layer of protection. However, I am worried that condensation will
quickly fill the airspace of the hose with water and it will either
penetrate the coax outer jacket or interfere with the performance of it in
some unknown negative way.

I can not flood the garden hose with petroleum oil as it will soon eat
through the PVC jacket of the coax or garden hose. Ideally, I would like
to flood the hose with the same stuff they put into underground cables. It
has a honey consistency and is not easily displaced by water. I was hoping
for some type of silicon oil but am unable to find anything similar at the
hardware store.

Anybody have any suggestions?

Get two rubber / plastic boots - the type used on electrical installations.
a large container of petroleum or KY jelly fill both end of the hose once
you have the coaxial through it this should stop any air getting in or out
and
so prevent the condensation problem. Finally put the boots over tube ends
again filled with jelly and using come electrical tape , tape over it.
Go over the electrical tape with self amalgamating tape them one more
layer of electrical tape to keep out the UV and "BOBS your uncle"
job should be a good one.
