Just got an '04 supercab....
Paint looks good, no real rust, and the previous owner under coated and sprayed a lot of areas of the truck.
However, everyone knows fords have rust issues at the bottom of the doors, cab corners, tailgates..
I'm mostly concerned about my cab corners and doors. Can easily replace the tailgate, not concerned about that.
What can I do now, to stop rust from even starting? My last ranger, the corners and doors starting rotting from the inside out.
I know the doors have drain holes in them they need to be made sure they are clear of dirt, but what else can be done to prevent rust from starting?
Take the door apart and paint?
I want my truck to last, and living in the northeast with the winters we get and mass amounts of salt they throw on the roads doesn't help.
Also, I do wash my vehicles a lot during winter, spray it off once or twice a week. I've read people actually spray water up into the drain holes to help flush... I have power locks and windows... If I do this will it damage the electronic parts?
i have a 1988 cab and fenders with over a million miles on it.....seen every winter since closing winter 1987.
there simply is no saving shitty sheet metel in the rustbelt when used all winter every winter on salty roads.
using the simple inhibitors, not wd40 only, maybe wd40 as a prep but it evaporates quickly. but a real light inhibitor as you intend is the best way in my eyes though. undercoating just destroys shit worse and makes it harder to fix later.
i finally had to fix my floors last year from total failure....my firewall is trashed as well. if i had left carpet in it and washed it all the time it would have turned to dust 15 years ago.
most of my income comes from working at remote locations out of doors, the work environment has heavy mud the majority of the time. so carpet is a bad idea, add to that i was a very avid offroader and wasting time and money cleaning the truck not a priority.
i am in the opinion burying my rig in mud every fall and packing it right up is why i have as much metel as i do.
not sure if i am right about that...just my experience.
but spraying stuff on the insides of the doors and gunwales like this
http://wd40specialist.com/products/corrosion-inhibitor/ with applications on the outsides i suspect would help through the winters....clean up in the spring with wd 40 and a good hot bath for the non bullshit salty slushy parts of the year should maximize life out of a truck.
WD40 is mostly water.
water? you would be the last man i would imagine to post such a wives tale.
it is a water dis-placer.....components of it are heavier...though most is just mineral spirits.
this is why it makes a great prep before some inhibitor for in the doors or what have ya.
WD-40's formula is a trade secret. The product was not patented in 1953 to avoid disclosing the details of its composition; the window of opportunity for patenting the product has long since closed.[4][7] WD-40's main ingredients as supplied in aerosol cans, according to U.S. Material Safety Data Sheet information, are:
50% "aliphatic hydrocarbons". The manufacturer's website specifically claims that this fraction in the current formulation cannot be accurately referred to as Stoddard solvent, a similar mixture of hydrocarbons.[8]
<25% petroleum base oil, presumably a mineral oil or light lubricating oil.
12-18% low vapor pressure aliphatic hydrocarbon, to reduce the viscosity for use in aerosols. This fraction evaporates during application.
2-3% carbon dioxide, presumably as a propellant, is now used instead of liquefied petroleum gas to reduce WD-40's considerable flammability.
<10% inert ingredients.
The German version of the mandatory EU safety sheet lists the following safety-relevant ingredients:
60–80% heavy naphtha (a petroleum product used e.g. in wick type cigarette lighters), hydrogen treated
1–5% carbon dioxide
It further lists flammability and effects to the human skin when repeatedly exposed to WD-40 as risks when using WD-40. Nitrile rubber gloves and safety glasses should be used. (Ordinary rubber is ruined by repeated exposure to petroleum products.) Water is unsuitable for extinguishing burning WD-40.
Wired published an article giving the result of gas chromatography and mass spectroscopy, claiming that its ingredients also make it resistant to freezing.[9]
