Lubrication Interval

After reading many posts about door lock pins failing, Slide outs hanging up and electrical gnd issues. I am thinking alot of these issues are due to poor lubrication or lack of sealing exposed wires.

I would like to know the interval that you use for lubricating doors, slideouts, mechanical steps, windows etc.

I RV in high salt environments and find when i get back to home base; spending considerable time washing and rinsing off salt spray. It literally rinses off as a dark soot salty material.

All the compartment lock handles have started getting corrosion pitting on them which is removed by waxing the turn handles. But is a good indication that salt is getting on the RV and is affecting the RV surfaces.

I have made it a habit of lubricating the door, locks pins, hinges. All the compartment hinges and locks, Leveling jack piston with silicone spray, window rails, step hinge points on a 6 month schedule.

I apply a light coat of lubricant on all the slide out gear rails, i then wipe the gear rails with a micro fiber cloth.

After reading many posts of failed electrical components, etc. I have started applying a clear flex seal coat to all exposed gnd studs, terminal blocks, fuse blocks, there are many.

After inspecting the water heater area, i see all the wiring is exposed to the elements through the compartments open louver's, same for refrigerator.

When we get a heavy rain, all is soaked with water. I have applied some flex sealant to the exposed wiring and circuit board. I have removed the cheap plug that was installed for the refrigerator during production and replaced it with an external purpose plug with plastic cover.

So far, i have not had any electrical issues, or faulty doors, pins locking me in or slide issues that strand us at a distant RV park, etc.

Underneath the RV, i have started inspecting all welds and applying the Black Flex Seal on any that are starting to rust.

I comment to my Wife, this all looks great in the RV showroom, but will all corrode when exposed to the elements. Is this overkill, or typical RV preventative maintenance?

Sounds like you have it covered pretty well

I use Teflon based lubricants due to many issues with silicone on some materials

Also, I have found the Teflon bases seem to have a longer useful life per application

I had the opportunity to spend some time with a Thor west coast factory service rep. His recommended lube was BOESHEILD T-9. He was emphatic about using it on the slide-out tracks. It doesn't build up as other lubes do. I've bought it from Amazon:

Itís good stuff but it was developed as a corrosion preventative. Itís lubrication properties are a side benefit. I use it for both purposes. More on my motorcycle than the RV.

I tried one can of Boeshield (parafin base) and the Teflon base is better for most things you donít want to stick

My experience is not on slides having only one small non hydraulic on the bedroom in the Landmark

Boeshield a an awesome product but it is not really a lubricant. I use it on battery terminals but use silicone for most moving parts. I use WD-40 on the leveling jack pistons. I do most of my items on a monthly basis.

What is the plug being referred to in the fridge?

WD40 is a cleaner. Has petroleum byproducts in it. Should not be used on your jacks as it will damage the rubber seals. I use the Teflon based lube.

If you have Schwintek slide systems, search on YouTube for lube methods. My book says not to lube the rack itself. But to lube the gibs.

While youíre going over it, look for spots of sealant either missed or very thin and split.

Since were lubricant and products minded on this thread i use several products for different purposes

Aerospace 303 protectant is a favorite as are their other sealants and detailers

WD-40 Is a great Water Displacement and Dielectric product and a modest lubricant in the original packaging, not the specialized products

For those with FLA batteries WD-40 is a great product

Teflon based products are similar but vary in price and solvents, find your favorite

Lots of choices out there and prices are climbing so stock up now

WD-40 is around 8 or higher now

Well done, it certainly is a labour of love. I swear by silicone spray and I use it everywhere, locks, slide walls, locker latches.... l even wipe it over the mirrors to try and preserve the chrome. Here, in N Ireland the air is almost always damp so, anything I can do to coat, lubricate and protect surfaces is good.

Boeshield T-9 is great for any exposed metal and for long term storage if you let it dry without wiping. As a retired gunsmith I have used it a lot.

WD-40 original formula was developed as a rust prevention product. It's petroleum based, so avoid long term use on rubber. I keep a thin film on tools which are prone to rusting.

PTFE (Teflon) based aerosol is an excellent all-purpose lube to use on just about anything. It will not attract dust/dirt like petroleum based products or silicone spray. I use it on window slides, door hinges AND my hydraulic levelers - which is recommended by Big Foot.
