Undercoating

[JayQQ97]

Maybe i'm not getting this, but is cosmoline suppose to do to salt that others will do?

this is a learning process for I and anyone else that might be curious about doing battle against that winter salt monster
since its my first trial & experimenting with the cosmoline product i was not sure what to expect with it and the reaction with dried roadsalt residue
the woolWax stuff, when exposed to roadsalt, turns blackish and you cannot see any salt residue
i am hunting for some pics for an example...

Idk, i used the regular amber cosmoline on my truck. Last 2 winters the chassis gets white looking from all the salt, and brine collecting on it. When it warms up on days, and rains the stuff wash's away looking as it did when i coated it. So far going into the 3rd winter season with minor 5 minute touchups, the truck looks no worse for wear.

.... am still looking for those pics

how about this in the meantime
It's bigger than it looks LOL

I suppose I am gittin nitpicky after all the laborious tasking LOL

Woolwax is lanolin based and wash's away if you don't keep up with a new coating every year or so. I doubt it would last very long on a chassis where i live. They all do their job...just comes down to for how long.

do you spray the cosmoline over ALL nuts and bolts on the suspension and everywhere else underneath, brake lines, fuel lines... all that jazz
i don't know how hard that stuff gets once it cures to be able to wrench off nuts and bolts when needed decades from now

so far i think the black is doing well on the 3rd member, i just hosed off the salt onit lol

Anything steel or even aluminum that can corrode from salt spray.I stayed away from the driveshafts, and plastic or any rubber components. Getting inside those boxed frame sections is a must. I removed some rocker panel grommets, and sprayed in there to, along with removing the engine skid plate spraying all the lines and steel pieces up in there. Removed the spare tire...hit the cross member and tire wheel plus chain good to. I went heavy removing the rear bumper caps spraying the steel bumper behind them plus the trailer hitch. I tried to leave nothing behind.

i bet your rig looks fantastic!

yep, its somewhat different out here on the western fringes of the rust belt, mainly with frequency of application i would suppose
a couple years ago there was a freak blizzard with a bunch of rain beforehand then the temps dropped and there was an inch of ice
they said F it to the sidestreets for the ice and just smothered that inch of ice on the mainroads with some nasty chemical that worked under zero F degrees.
those huge SALT sicles that accumulated in the wheel house liners was obscene

they have YET to salt the roads here since there have been no flurries yet but its well below freezing in the evenings and 50s during the days
all they have salted are the bridges and overpasses freeway exits and such
maybe make it to December before there is white salt dust everywhere from a 1/2 inch of flurries expected wednesday after a nice rain that they cannot pre-treat roads so BOO on them LOL

 

[JayQQ97]

I am finally trying this BOEshield product developed by the BOEING corp... they make those JET airplanes out in the Seattle area or somewhere
i have a nice test area on the frame where i had to remove the primercoat from a few years ago because it looked like it was peeling and crusting under... i put some phosphoric acid onit to prevent flash rust and now coating it with the BOEshield to monitor any frame rust on that most exotic metal they used to build these taco trucks

All i know is between all the salt and brine they use on roads here, mix that with lots of slush, and wet roads, you'll end up with a chassis thats old before its time. I've had trying the lanolin based rust inhibiters...too much work every year, plus no one close by that does this professionally. So far i'm happy with this cosmoline stuff.
So far we've only gotten some light wet snow, no salt ...its been raining a couple times a week, even currently as i'm typing this. Less salt the better.

what undercoating is suggested for the transfer case housing... I believe that is aluminum? and corrodes differently from weathered pics I have seen.
.... just don't wish for mine to start getting yuck like that

Nothing...after 19 years the aluminum transfer case in my tundra looked fairly new yet vs the rest of the chassis that wasn't.

maybe the pics i have been spotting are from trucks that live near to the ocean? and why they are so nasty
but i also notice under the hood on some pis the plenum that is caked in corrosion, including one of the recent trips to Chicago area on a '99 T4R

Any vehicle made with steel thats parked near the ocean front is going to get nasty, especially if they launch a boat there, and never wash the trucks chassis when finished.
Right now its been the monsoon season here, seems its been raining every other day for that last couple weeks. Had some wet snow mixed in.

does your county go back out after all this rain and resalt those roads, bridges overpasses

its an absolute desert here still,,, farming communties along the missouri river upto south dakota are in major severe extreme exceptional drought this year.... nearly 15-20 inches of rain/snow below normal if i had to make a guess...

State will brine the highways 12 hrs., or so before an oncoming snow, or ice storm. The towns only salt the roads during, and after a storm. Has to be snowing or freezing rain for that to happen.
We had a very dry summer, and early fall, but its been making up for it lately.

Brine is applied early. This way it can dry on the road surface. It will become active when the snow or freezing rain hits it. The purpose is to prevent the ice from forming and sticking to the road. The plows have a chance to blade the schmutz off the roads. Be grateful the brine is applied. The roads would be a utter disaster without it.

Salt is only effective when the roads have a covering of snow or freezing rain. Road salt loses its effectiveness below 15F. The downside is that 15F is a "warm" day in IA winter.

What kind of chemical junk do they use to destroy ice when it's below zero fahrenheit?
