If you live anywhere other than the dry and sunny Southwest then you know how much of a pain rust can be. Rust is that silent assassin that works night and day, chomping away at all of your exposed metal components. With nothing more than a little iron, oxygen, and water, rust can age even the most modern and well-built rigs in virtually no time at all. But there is a way to fight back and protect your 4x4.

While many late-model rigs are equipped with extremely durable undercoatings and composite materials to better protect the framerails and body, there are still plenty of vulnerable areas. Fighting rust before it becomes an issue is always best. Spray lubricants, routine maintenance, and aftermarket components are just some of the ways to keep your 4x4 from falling apart. Compiled here are some of the tips and tricks we’ve learned over the years to combat rust. If you have some rustproof ideas of your own, go to our forums at www.4wheeloffroad.com to join in the ongoing rust battle debate.

Both high-performance and entry-level shock absorbers often fall victim to rust. Since your rig’s tires are constantly throwing around dirt and debris, your shocks often see accelerated wear, thus leaving the shocks more vulnerable to rust. An easy way to protect and clean your absorbers is by spraying them with WD-40. Using a Scotch-Brite pad with the WD is also helpful to remove corrosion buildup. Daystar also offers new polyurethane shock armor to protect against gravel rash. Both high-performance and entry-level shock absorbers often fall victim to rust.

A common misconception is that aluminum is immune to corrosion. While aluminum cannot rust, it can still fall victim to galvanic corrosion, pitting, and crevice corrosion. Vehicles near the sea or where road salt is heavily used are at a higher risk. If your aluminum parts are showing signs of corrosion, an excellent way to bring them back to life is to have them sandblasted and then powdercoated. This will seal the surface and give your parts a fresh look. A common misconception is that aluminum is immune to corrosion.

One upgrade that we’re big fans of is ditching any material that can rust altogether. Fiberglass replacement panels, such as fenders, hoods, and bedsides, are great ways to lighten up your 4x4 and eliminate the risk of rust. While switching to glass isn’t cheap, it is a stylish and extremely effective preventative measure. One upgrade that we’re big fans of is ditching any material that can rust altogether.

Two items that are must-haves for anyone working on a rusty pile is a can of PB Blaster and a butane torch.

Loctite is a great way to keep a bolt from coming loose, but so is rust. On hardware that gets routine service, be sure to add a small coating of antiseize.
