I use Fluid Film.

I spray inside every hole in the frame rails, inside the shock mounts, anywhere that the tires will spray on.

I spray inside the body cavity anywhere I can pull a bolt and spray inside, as well as remove the tail lights and spray heavily in the back. 3-6 cans depending on if it is the first time ever, or the yearly touch up.

It works pretty good! It smells terrible.....my wife hates when I apply it each fall to her van. After 5 years, the van only has rust on one dogleg where it was already blistering when I bought it. No new rust anywhere else.

None... but it pays well.
Why not kill two birds with one stone? FLEX SEAL spray can will do sound deadening and keep your underside protected. As an added bonus may even keep your jeep afloat. Ha!
