There are many different companies out there doing rustproofing. Some spray-on a tar-like substance that hardens. Others, like Krown Rust Proofing spray an oil that has to be reapplied every year. Some of the brands that I'm aware of are Ziebart, TST Protection Services and Krown.

What everybody's opinion of the different options out there? What are some other alternatives?

 

Fluid Film is popular on the Toyota forums.

 

I've heard interesting things about this stuff. I'm interested in this topic for sure. Getting a new truck soon only because my 98 has all but rusted away. Engine and tranny run like a top but 20 winters with salty roads have destroyed the damn thing. I'd like to prevent that on something new...

 

I have used fluid film and krown. Now i use formula 3000

Any opinions on the three?

 

I would just buy an Aluminum truck if I were worried about it.

 

Aluminum corrodes...

A lot of Ford hoods have been aluminum for a long time (Since 1997 on F150). You see "White Rust" on aluminum. I would prefer my truck not to have the paint bubble up like the picture bellow.

 

Yeah, but rustproofing isn't going to stop that, is it?

Don't know anything about white rust unless you are referring to oxidation on exposed aluminum after the paint fails. The condition in the picture is likely not caused by the substrate material but more likely poor preparation or cleaning of the substrate to accept paint or a defect in the chemical make up of the paint or a reaction between elements of the paint job itself. We had the white paint flake off like that on all of our departments white crown vics affecting the years of 2005 -2007 So much so that ford footed the bills for all of the affected panels and in some cases whole cars to be repainted locally. The hood, trunk lid, roof and pillars were most often affected and some fenders as well. I would suspect some unknown airborne contaminant or residue on the panels that panel prep did not remove completely interfered with the primer coating. My 2016 Xl already has surface rust on undercarriage parts that with some careful shielding and masking will get painted black this spring. As far as the body I think any rust proofing is unnecessary on these trucks if you live near the ocean or in northern states with road salt maybe on undercarriage parts and frame might be advisable. just my 2cents

 

It won't help the body panels in the slightest, I'd actually be careful of what chemicals are sprayed because it could cause aluminum to corrode. That said, it would help the frame and axles.

My mom's '01 expedition is doing like the above picture. It was due to leaves/moisture building up under a bug shield on the hood. It caused the paint to bubble as shown.
