Superglide Hitch Rust

[RVhiker]

I have the new "improved" Pullrite Superglide Hitch - the kind with the plastic pads with which Pullrite says to use WD40 as a lubricant. I agree that WD40 works well, in this application, to lube the plastic and the rails. It also seems to cause the metal rails to resist forming rust when wet, at least for a while.

But, even if the rails are cleaned up and fresh WD40 applied, the rails will rust, and fairly quickly. Has anybody found a solution to this rusting? Maybe using a grease or much thicker oil when the hitch is exposed to the weather, but is not in active use?

I've not seen any rust. WD40 is all I use. My pullrite has the plastic you describe... I think. I've spoken with the PullRite folks many times and found them eager to help.
They answer the phone and emails promptly (at least that was my experience)
Here's a link to ask them about it.

Please post what you find out and your results.

If you want to stop the rust apply Fluid Film. It penetrates the metal, we used to coat all of our salt truck beds with it.

Home Depot, Lowes, Ace, Menards and the auto stores have it.

I'm thinking... will post back if I find out more. Thanks!

About four weeks ago, I bought some Fluid Film. I wiped off he Superglide rails with a paper towel and some solvent, and then applied a light coating of Fluid Film to the rail tops and inside rail sides. For about four weeks, the Fluid Film protected the rails from rust from our spring rains and one hurricane passage. I am amazed at the effectiveness of Fluid Film in protecting against rust. I cleaned up the rails from miscellaneous bird crap and tree debris today, applied a new layer of Fluid Film, and I think the rails will be good for a month or so; WD40 may the best for lubing the hitch rails when in use, but WD40 protects the rails from rain and rust for only a few days.

My thanks go to Grumpy for suggesting Fluid Film.
