Re: slide outs spray for metal parts

I have double rails with teeth that are driven by gear assembly that is actuated by hydraulic piston.
Rails are exposed to elements...............mfg. states NO Lubricates. Just wire brush.

So I wire brush them down.....and then give them a light coating of dry graphite spray.
Piston rod.......wipe down with cloth to remove any dirt/dust then another wipe down with a cloth with silicone spray on it

Slideout seals/wipers........talcum powder

7 yrs. all good
