Very simple to control rust if youre not a total idiot

 

Simple but lots of work (rinsing the underside every time you get on a wet highway during the winter)

Denver started using Mag Chloride, and I can visually see rust forming on parts that I have installed ~ 2 years ago, and I even use fluid film on major stuff in the fall

 

Yep! Totally agree.
Been meaning to do that but haven't got around to it yet.
These days my xj is more or less a fair weather driver which is why i talked myself into delaying it.

Here's how i intend to do it, right or wrong.
When i get around to it i might try to find some replacement stainless screws then coat them with some to be determined rust preventative stuff to minimize rust against the threads/steel rail.
If i can't find stainless i'll still coat the screws and hopefully enough rust preventative will remain on the screw to minimize the screw from rusting internally in the rail.

Then clean the screw head and wire wheel the surrounding area to bare metal then paint over maybe with bed liner paint.

 

A little rustoleum goes a long way.

 

Tell that to members that live in North Central US - road salts

Most real hardware store carry stainless screws & bolts these days.
Smaller chain stores Ace, McDaniel's, True Value, the big box stores have limited selection, & pre-packaged quantities.
try Googling Bolts and screws. the Screw / Bolt industrial suppliers will give you a much better deal but may have a minimum purchase.
I use Champion Bolt, or Tacoma Screw when buying more than just a few.
