Best Lube for undercarriage.

Ever since my dad shipped a full case to me in 1966, I have been a fan of Dri Slide. If it's good enough for an M2A1 and M16, it's good for everything else. All dry lubricants are not the same (school of Hard Knocks). This stuff seems to last 5 times longer than other brands of dry metal lubes including those containing graphite and molybdenum. Ain't cheap, but it's economical.

Big Fluid Film user here. Do my 2003 Winnebago every year. Well worth doing. It is not a dry film and will attract dirt and dust.
But from my perspective, that is what is needed to create a nice water proof patina to keep from rusting.

I use it too but it has another use. It keeps mice away as they don't like to get the stuff on themselves. I buy it by the gallon and have the sprayer so I recoat every year or two depending on how it is looking.

Ordered a can of this stuff early this morning. "DuPont Teflon Non-Stick Dry-Film Lubricant".

I have a new trailer and want to keep it that way. No rust and I do not want something that will gather dirt and dust. Used to use "Tef-Lube" but no local dealer and it is almost $18.00/can online.

Fluid Film will prevent rust and lube the springs. It is lanolin and can be sprayed on anything other than the inside of the brakes. It will need to be re-applied every year or two and will keep everything looking new.

from the way i read it.
it sounds as if he just wants to know what is best to keep them lubed up and free of obstruction for flawless operation , squeak, or any other issues that may arise from use. but, if he does want to fight rust only. we can answer that way as well.

I think :h the OP is talking mainly about rusty areas.

if so i am surprised that more people do not use lime green stuff that is used for bare metal prep. Found my last gallon at home depot. It is the lime green stuff in the metal prep section that contains phosphoric acid. i put it in a spray bottle and spritz it on. Watch out for your eye balls.

Phosphoric acid plus iron oxide equals iron phosphate which is inert.

007 dry spray on lubricant.....Glass shops can order it. WD 40 is good stuff too, I use it alot to prevent rust mostly. Yea dirt sticks to it but I pressure wash it off, then re apply when I need to, I like it.

007 made by spray way is great too, especially for door locks, latches and the such. Problem is it's not cheap, WD 40 costs much less, and you get more.

Dry graphite spray.

NONE of the above ... instead, The Solution from Krown quiets anything that squeaks ... don't leave home without it. :B
