    How can I prevent it? I just climbed under my truck to look at my leaf springs, and noticed that my frame and under carriage is starting to surface rust, only one spot had a little pit in it.

    Its a 06 37k miles, I want to hang on to this truck for a long time.

    Am I just being paranoid? Already worrying about rust?

    Anyway how do I limit the rust?

    This is my first new(er) vehicle and I owe money on it, I thin thats why Im so paranoid about it lol

    Thanks and reps!

    I have it too. I noticed it the worst though looking down at the frame through the engine compartment. I think road salt tended to wash up and lay in some places. I gave the frame a good hose down and sprayed places I could see in the engine compartment with soapy water just to try to get the salt residue out last spring.

    Haven't done anything else though.

    What else is there to do I want to keep her around for awhile.

    I know I need to get a stiff wire brush and get at the rust (I think anyway Im waiting till confirmed) then possibly just use some rhino lining stuff (the spray can).

    I wouldn't rhino line. I know that when looking for an older car, you tend to avoid ones that have rust protection plans, because they just hide the problem.

    I would scuff it to remove the rust, but then you would have to apply some sort of primer or rust prevention paint. A think coat of the tar crap or rhino liner would prevent you from knowing if the rust issue is still going on. With paint and primer, you will be able to see it bubbling, and you could just sand the area down again and spray the area again.

    Just sanding the area alone will not be enough, as rust will form again. You need something to seal it.

    They don't hide, they correct it.

    To rust, you need two elements: air (O2) and water. Salt is worst because they accelerate the rusting. By putting a anti-rust paint over it, you're blocking air.

    That's the idea of anti-rust oil/wax traitement and any other specialized products like POR15 (it's thick).

    I use it and I can confirm you: when well applied, it works, rust stops.

    I know what you mean. I'm debating on what to do with my '10 Taco. Ironically, on my '99 I had the truck undercoated five years in a row (or I guess one undercoating and then touched up) and in July the factory bought it back from me due to the frame rust issue. Guess my undercoating didn't help. With this truck, I can't help but wonder if it's just a waste of money to try and prevent the inevitable. I was thinking about it the other day but back when I first got the truck and was 17, I noticed some rust when it was a couple of years old. Both the dealer and my father told me I was paranoid. 10 years later I guess I proved them both wrong.lol

    See that's the thing I'm not sure if I'm just paranoid.

    so you say POR15 works. So do I just get a tough steel brush and get the rust off then put the POR15 on?

    I would rather try and stop it, even if it doesn't work at least I tried. I'm going to mention it to my dealer who I'm sure will say its normal. I'll upload a pic later

    Inouk- I know some can do it right, but I've seen cars that have rusted out with that stuff on, and the owner doesn't realize it. In my experience, I would avoid doing that. Just my $.02.

    About twice a year get under there and sand and paint with some rustoleum paint. I use a wire brush and a wire wheel at the end of a
    cordless drill. You do that twice a year, you will be fine.

    Do it before winter, then right after.

    Well, this type of thing is like so many topics in that you will have some say yes and some say no.

    I usually avoid undercarriage spray, but inouk swears by it. I would suggest researching the product and if you do it, follow the instructions to a T, to ensure is works properly.

    I agree with Ebbs... I dont like the Rhino spray on the undercarriage because when you need to work on the truck, you have to scrape all that shit off the nuts and bolts. Paint is not that thick.

    Dude, I know where your at..... When I bought my 07 it looked like it sat in a swamp for 3 yrs. :eek: However, thats what it looked like but most of it was just surface rust and did come off rather easy.:rolleyes:

    After a good Northeast Winter, Im sure in the spring it will be back again.

    There a lot of good topics here about rust and how to treat, just type in the search category on top.

    Yeah its going to be a pain crawling under it, brushing it off (most looks easy as you said) then spraying it and it blowing back in my face while its 38 degrees outside LOL

    winter is almost here (snowing) so I want to go ahead and do it.

    I want to try and keep her rust free I love her.


    I checked under the hood as someone said it was and under there where you could see through I was surprised hardly any was there its mainly my frame.

    Also my axle is pretty rusted should I go ahead and do that to i dont see why not.

    Wash it once a week in the winter if possible, shove a lawn sprinker under it let it rise the under carraige, when I wash in the winter I make sure to rinse the grille area real good as road salt gets sucked into the radiator.
