Rust Prevention?

[Janimal444]

WIth winter around the corner, I was wondering if you guys had any good tricks for rust prevention. I usually just try to keep the bottom door seams lubricated with WD-40 or oil, and I usually wire brush my frame, and hit it with rust-converting primer then spray can undercoating on a regular basis. Some say this does not do much, but obviously sealing off a rusty spot from oxygen is going to slow down the corrosion process. Anything else I should be doing? Luckily my truck is not a DD, but it still makes the trip up north snowmobiling on some weekends.

Don't drive it thats your only defense! This Calcium Chloride they spray ion the roads is a killer! It creeps into every Crevasse!

Best thing you can do is treat any bare surface keep up the wax and wash (rinse) your truck off as much as possible! Specially the under carriage! Use the garden hose and sprinkler at home for the under carriage on warm days.

I usually pressure wash the whole rig as soon as I get home from a trip:thumb:. I have come home Sundays at 10pm and been out in the 20* weather pressure washing haha.

But yes, the salt is brutal they use now. I want to get a LB7 daily driver so that I can put the rig away for good in the winter, as I agree that is the only true defense.

Chassis saver for the win.

Comes in a gallon paint can, you can brush it on or delute and run it thru a paint sprayer.

Do they carry this at auto parts stores?

I'm heading into my 7th salted winter with this truck. 120 miles a day 5 days a week. Still relatively clean and no body rust to speak of. What I do is run through the super wash with undercarriage flush at least once a week. I park in a shop (overnight) that is above freezing 99% of the time and on weekends it gets a good hand wash (including inside the doors) in a 60*+ shop with plenty of time to dry. Works for me. I don't have the time (or energy) to do all the re-coating/detailing on the undercarriage so it DOES show weathering somewhat but not bad for its age.

I got mine on line and had it shipped right to the house. But some of the local body shop suppliers had it in stock it was a little cheaper to order on line and I didn't have to go chase it.Just a tip don't wear anything decent and wear gloves it doesn't come off skin.took over a week for it to come off my hands and a couple spots on my arms.You can apply this to light rust no sanding needed and after it dries it's hard as a rock.It's awesome stuff.

Thats a big part washing it once a week. I find that ,that works even on my CJ7 to keep damage at a min.

If you are going to take the time to wire wheel the frame down that would be the time to paint(roll/brush or spray) POR15. It is supposed to seal better when it contacts moisture they say.

I completely covered my undercarriage when I did my SAS swap. Frame, axle's, and all brackets and tabs. You could even coat the underside of the body if you prepped it as well. I would strongly suggest using their paint prep items that go with it. You will spend about $200.00 on everything to cover the totally underneath of your truck but if it's prepped right and let it cure up you most likely will never have to mess with it again.

Well I hope you have better luck then me with POR15 .In my opinion it isn't worth the money.

I bought a brand new windshield frame for my CJ7 as the old one was rotted. It came in primer which was sanded to bare metal on the outside then ETCHED or what ever they call for to prep the steel then the POR15 applied inside and out then painted finish coat color.

Well two years later the frame is rusted to shit!!!!!

Yes the windshield leaks and moisture can and does accumulate in the channel BUT in my opinion it should not rust like it has!

On edit: I know it's all about the prep with POR15 and I do feel I did a adequate job to get the advertised protection. For a FYI I have used it previous AND elsewhere on the Jeep WITHOUT. Recommended prep and it has held up or fairs better. Just pisses me off as swapping windshield frames do to this Jeep being a mutt, 83 front clip includes windshield,87 tub is a big job!

You just have to keep up with it. I have two trucks a 03 and 04 and both are super clean. All my polished wheels I keep a constant coating of wd 40 on and I pressure wash the vehicles after every trip as well as prep the undercarriage every season with cheap flat black paint on the bare spots and I'm in northern Ohio. Now I recently got this bees wax type liquid from my body guy it goes on then the viscosity somewhat firms up after it settles. We did all the hard to reach places such as under the hood in the fender creases. We also went as far as drilling the rockers underneath filling them up and capping them off. I will try to get the name of this stuff. Oil spray also works.

That's exactly what I do and it has worked well for me. Even my '94 Silverado Plow truck has JUST started to see rust on the rockers. Not bad for an almost 20 year old vehicle in New England.

Also, I'd be interested in that wax liquid, let me know if you find the name, thanks.

Hmmm sounds interesting. I always thought this stuff was like a heavy coating like grease to prevent rust on stored parts never in this application you're mentioning. Or maybe when applied heavily thats what it pears to be? My experience is the airplane prop that I have off a C30 Transport (I believe) is coated with this stuff!

Might pick some up and spray the Jeep the WINTER beast!

X2-but a bit pricey...
Wonder how it holds up to a nice steady salt spray but kinda sounds like that thick wax crap they douched on at the factory that actually holds up fairly well.

I'm not so sure washing does more good than harm. My work truck isn't washed but 1 or 2 times in the winter compared to mine every 2 weeks or so and the work truck has no rust compared to quite a bit of corrosion on my dmax. fluid film works good as a rust preventative most times.

Try that in the great white salty north and report back with your findings...

 

[arneson]

The only time washin a vehicle does harm is when u dont get all the salt off and u let the white film. Get wet and activate. Best prevention dont drive it in the salt, if u have to for whatever reason wash it often, most people dont wash the undercarriage like they need to or should. A good wax to protect the paint, and heated garage doesnt hurt either. My trucks, sleds all get same treatment and u couldnt hardly tell they see salt.
