Quick video of my F350 undercoated with NH Oil Undercoating.
Anyone else using New Hampshire oil undercoating?

I have 2 boxes of stuff from them that just came in. Plan on spraying my truck in the next couple of weeks.
How much did you need for the chassis only? I got 1 gallon of black for the chassis and 1 gallon of clear for the cab/bed if I do it (aluminum bodied truck). I called to ask them and they said a gallon should be enough for a F350. If I sprayed body cavities they said a gallon and a 1/4 to a gallon and a half. Also got their salt brine remover with the foam gun. I got their DIY kit with the sprayer and wand extension.
What air pressure did you spray yours at?

You'll be glad you did, stops rust from growing. I put it on pretty thick so for the whole truck I used 1.5 gallons. I would guess you might be able to away with 1/2-3/4 gallon on the chassis alone. I used 120 psi to spray.
Huh. I thought this thread was going to be about leaky power steering pumps.
After my last Truck was destroyed by rust I wasn’t going to let it happen again. I bought a 2017 F350 that is in very good condition as far as the rust department goes. Thanks for the tips.
A local mechanic near me does NH Coatings spraying at his house as a side business. He sprays black on chassis and more of a clear color on other areas. They mixed in peppermint this year to repel mice.
In the spring I go to a different shop to have CarWell sprayed.

Tried to do so when I was up in NE recently, but shops were booked solid.
Will probably order some to diy...

That’s your best bet. A DIY kit with a gallon of the black undercoating, a spray gun and 18” wand is 140$. I also bought a gallon of the salt brine remover, the foam gun for it, a gallon of the clear undercoating and some body suits. Total cost was 295$ with free shipping. A small price to pay to protect your investment

Ive been spraying cars with salt away and a fertilizer sprayer for years.
I have the wands, and a spray tank, which is IMO much better and more convenient than a gun with a tank attached to it.
Wish the spray tanks were more available/cost effective...
Which "spray tanks" are you referring to? I'm suffering from a brain freeze this morning. Thanks!
Do you typically have rodent problems?
Wife's Subaru seems to attract them. But not the Ford. I found two dead baby mice in the Subaru and the car smelled of dead rotting mice for months. I assume in the dash area.
We have a Mouse Blocker Pro in each vehicle.
I have caught 5 flying squirrels in the attic in past few weeks. And many dead mice in basement.
Remember NH Coatings suggests to not have any undercarriage spray at car wash after spraying.

Ones very specifically like this:
which was a screen shot from their site:
https://www.corrosionx.com/products/handi-spray-application-systems?_pos=1&_sid=ba1776fe9&_ss=r
I actually have a small size one thst was broken (picked up on eBay cheap), and the 2.5 gal one. Id like another, maybe two, to shoot different materials with, but they’re expensive, like $750 or so, for a propane tank and hose.
What is unique-ish with these, is that there aren’t two lines to the spray gun and wand. There are other spray systems that have an air assist, and two hoses to the gun. There are also types that have all the material in a bottle or tank attached to the gun. Very inconvenient especially when trying to get to spots under a vehicle without it on a lift.
I think it’s some variant of the airless sprayer concept, except that the air is actually pushing the material through the tubing (Which makes it not airless of course). I suspect there is an analog in the paint spraying world but I don’t know what it is...
The Corrosionx site claims their system creates a fog. I wonder if their tank design somehow creates this or is it simply in the gun/nozzle?

It’s the nozzle IMO. I don’t really know how the air gets consumed, maybe it blends or creates a Venturi in the part that connects to the tank.... but the end of the wands has a very specific compression that causes it to mist.
I was not happy with them. I had an 09 Escape that rusted out both inner wheel wells and rocker panels after years of going to them. Half way through winter I couldn't tell anything was applied. The same seems to be happening with another company.
YMMV
