...see pic..wondering if I can clean up with rustoleom paint and rust inhibitor or maybe por15. ..it's under carpet so I don't care what it looks like...could use advice thanks..would like to be relatively inexpensive

If it were my jeep I would try to grind away the rust to see what you're left with. Doesn't look extreme but it doesn't look good either. Then replace it if needed, if not then primer and paint it up

Grind it down and por15 or chassis saver it... Might be time to strip down the interior, clean it up and bedline it.

Sand that bad boy down real good and see if it still holds strong. If it does, spray some rustoleum and is say line it. I herculined the entire floor of my jeep and it's fantastic. Put your jeep on a lift (or lift it yourself) and Spray some undercoat. (Make sure not to hit the drive shaft, etc) you'll be good from both sides for a long while.

That just looks like surface rust. I would just get it good and clean and use some POR-15 on it. You don't have to get all the way to clean metal. (POR =paint over rust)
