I read that people are basically coating the underside of their trucks with wd40 and it works... seriously they say it's like treating bare steel to prevent rust

 

to me, it seems like an ideal grime collection tool? although, i guess it would be easier to wipe off??

 

never heard of this but i just did it, lol... i guess we'll see how it goes.

 

truck is only 3 months old, it just rained and all the crap seemed to have been gone so i sprayed her up

 

thoughts?

I knew a guy years ago that ran mud trucks. He swore by it and said it aided clean up tremendously. I am pretty sure I saw an episode of Extreme 4x4 where they reccomended it before mudding as well.

I coated the underside of my 08 with a product called Fluid Film, it's slightly thicker than WD40 and seems to help keep the rust out of there so far.

I could see how that works but I too would be afraid if the dust and road grime just sticking to it.

I read in a 4x4 mag that alot of mudders spray PAM cooking spray onto plastics and body panels! Mud just slides off!

I've never done it on my truck but I do it on my dirt bikes all the time. One of the MX tracks I go to is red clay mud that takes hours to get off the bike, especially in the hard to reach areas. But, a healthy coating of WD-40 to all those areas before I ride and it mostly rinses right off. Cuts clean-up time to less than half!

 

WD-FTW!

If there are raw areas then wd will promote rust. I used to spray it on tanks I was building and the next day you could see the start of rust. Now it could also have been the acid content in my hands. Who knows. Spray a little on a bare spot first to check.

I've used WD-40 on all my trucks,I spray it on,let it soak for a little bit,then wipe off the excess...works great,and helps keep the underneath of my truck nice,clean,and rust-free.

WD 40 is a great rust prevantative, it's durability is a tad suspect though, washes off too easily. Up here (Ontario, rust capital of the world) rustproofing a vehicle is required as far as i'm concerned...you'd be amazed at the rust (surface) on a year old vehicle's underside...and the completely rusted out brake and fuel lines after 7 years or so.

 

We're lucky enough to have to very good options, rust check and Krown...both are a little messy, but work great

they use either salt sand mixture, or straight salt...some of the major highways use the magnesium chloride liquid spray which is even worst than the solid stuff. I'm sure the roads there are similar to the ones here so i'm sure you can attest the fact that these vehicles do not come with adequate rust protection from the factory.

well... so far so good. It seems to last through driving in the rain, at least enough to do what i need it to. I'm going to keep doing it, if it'll prevent bare steel from rusting, it must be a good thing.

I remember two winters ago.. had my truck undercoated right before snow started falling. Half way through the season almost all of the undercoating was gone!!!!!

Personally, that is the LAST thing I would have done although I doubt it will hurt anything. That's not necessary at all on a new truck.

 

Wannna bet? New stuff rust dude.... And the sheet metal is thinner than ever before.

 

I knew a guy years ago that ran mud trucks. He swore by it and said it aided clean up tremendously. I am pretty sure I saw an episode of Extreme 4x4 where they reccomended it before mudding as well.

 

When I use to play in the mud with my old 1996 F150 4x4.... I would swing by walmart and pick up 2 bottles (the larger ones) of baby oil (GET THE NAME BRAND the off brand DON'T WORK as good). The sprayer was a 3 gallon unit... I would one bottle of baby oil to 3 gallons, it took 6 gallons to coat the entire truck underneath and everywhere less the roof.

 

My buddies would spend 20, 30, 40 bucks washing the mud off.... 5 bucks I'd be clean as a whistle and pulling out of the car wash (5 bucks included washing my boots and vacuuming the truck out tooo). I never told them what I did hahahahaha... Cruel ain't it.......... I never did show anybody how I did that but now you all know about it.

 

It could dry on for 24 hours and it would still fly off with a little pressure...

      Mangoal or FitcamX OEM Dashcam?

      By MANGOAL · Posted

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
