Frame Rust...

[Mad Maxx]

Does anyone else Think that their Truck has an Exceptional Amount of Frame Rust?

My Truck is an '07 and has 37k Miles on it, and IMO has FAR too much Rust on the Frame for how much I Drive it. I always Wash it, and when I'm Down by the Beach and it's High Tide, the Road Floods, so as soon as I get Home, I Spray Down the whole Under Carriage.

My '97 Cummins had pretty much 0 Rust Under it (59k Miles) and my '05 Wrangler has 0 Rust as well (37k Miles) AND it gets Driven on the Beach. Combine the Amount of Rust that Both of these Vehicles have, and Honestly, it's not even 1/6th of what my Duramax has.

What gives?

I would say that my 2006 has an average amount of rust on it for having 84K on the odometer. The road salt in the winter kills the undercarriage. I do not wash mine nearly enough. I would hit up the rust spots with a little black Rustoleum. It does wonders.

I've prob. gone through 3 Cans of it by now. In a few Months, it Disappears like it wasn't even there

My old 88 dodge frame had very little rust compared to my GMC, I hate to say it but I think the dodge frame is made from better metal.

My 2006 truck has 44,536 miles on it and it still looks pretty good due to the fact that I kept it out of the salt for the first 2 or 3 years that I owned it. The last 2 winters were tough on it being that I drove it a bunch in the snow. Where I live they use the road salt plus chemicals such as calcium chloride (I think?) Those chemicals have been eating people’s vehicles up at a faster rate compared to regular road salt. Thank goodness this winter was mild and I think I only saw salt on the road about 4 times total.

I try to keep it washed off, but I think the best you can do is still not enough. I often wonder if a vehicle sits alot, if it makes it worse. Other words moisture builds on parts and it has an effect on it. I have a few rust spots on the frame where the wax coating has rubbed off. Like Silverdoman I hit those spots with the black rustoleum. I hate rust on anything.

I'm just Baffled by how much Rust is on the Frame already Compared to other Older Vehicles I've Encountered.

6 Winters and 188k. Yeah there's some rust but not as bad as any other truck I had previous. I run through the super wash with the undercarriage flush weekly. Seems to make a big difference.

We dont have many of those in our area, gotta crawl under so the undercarriage gets pretty nasty on mine.

168K and I have rust, been touching up but fixing to try POR 15 (once I find a place that carries it)

Seems like there is no actual 'paint' on a factory frame anymore... They just squirt this tar-like crap on bare metal.. Then the rust starts undermining the layer as the tar-like crap peels away. At least paint holds 'tighter'..

My 06 had rust on all the welds where the body mounts met the frame and the upper control arms were rusty. Not just surface rust and it never saw salt a day in its life.

My 98 does not have much rust on it but we are 15 miles from salt water and they really only ever use sand on our roads. I never drive on the beach, that's asking for problems.

Get some of that Purple Power De-ruster or one of the similar products. it sprays on and turns any rust it touches into the usual black polymer. You will need to scale all the loose bits off first. Mine no longer has an exceptional amount of frame rust :hihi:

I didn't know Purple Power made a De-Ruster. I thought they only made De-Greaser. I'll have to Look for it next time I'm Out.

I think Rustoleum also makes the same type of primer. It bonds to the rust to form a good base. Neutralizes the rust supposedly.

The stuff I am talking about is not paint. Its a thin spray like window cleaner that converts any rust it touches to black oxide. Another brand and the last version I got at Advance is Right Stuff Formula 3000.

The hood of my Olds was doing the typical surface rust thing and I didn't want to take it down to base, etch prime that and paint. Just wanted it to look passable. So I gave it a quick sand with 200# and sprayed on the Formula 3000. The rusty bit turned black, this stuff gets down into the micro pits where you could never sand and kills the rust and leaves a slight tackiness that paints fine. I let it set over night and then painted it with a couple of rattle cans. Now years later the top I didn't touch has the same surface rust but the hood, though faded has none. :thumbsup:

I am going to use this a lot when I do up grandpas tractor.

I would wipe down new bare metal with this stuff to prep for paint.

Isnt that what por 15 does?

Isnt that what por 15 does?

Yes, but way more involved on prep it seems.

I got 2 cans of POR-15 in the Garage, but they are Ooooold, and prob. no Good anymore.

Here's some Pics of how the Frame Looks:

James, I think between the salt in the air and driving through salt water it has really done a job on it. Flushing the underside with straight water might not be neutralizing the salt on there.
