It’s caused by water
I live in Louisiana, plenty of water around. The rust on vehicles up north is due to salts on winter roads, not from rain or gutter water.It’s caused by water

It's both. Salt and water, and freeze/thaw cycles.
Sometimes I miss MI...thanks for reminding me of the miserable winter slush...Hi folks,
I've seen a few threads on initial rust when vehicles were delivered, but nothing long term. Figured this might be helpful for folks wondering about where the typical spots for rust to start might be and where it is a good idea to focus on rust prevention.
My truck was built in March of 19 and I bought it from the dealer in November of 19, so it has been through 3 full Michigan winters here as a daily driver. They do not spare the salt on the roads here and I've not done anything to it in terms of rust prevention, undercoating, or washing regularly in the winter.
Front fender well, we can see rust starting at the welds ahead of the tire. Some fasteners with surface rust as well. A little bit on the frame area behind the tire as well.
Rear fender well, again welds are where we see rust starting to grow.
Frame in middle of truck looking rearward. Same story here, some surface rust at some of the welds, otherwise frame looks good.
Frame just behind front wheels. This is the worst area, seems like it takes the brunt of the salt spray from the front wheels. If you're spraying any type of RP on the underside, get every nook and cranny in this area.
Rear behind the back wheels. This fared better than the front. The spray must miss most of the underside.
In summary, surface rust seems to like to come through wherever there is a weld. The area behind the front wheels is the worst, but there is no corrosion anywhere on the body itself, only frame and hardware. The mechanical bits themselves (diff, driveshaft, ect) also look mostly clean. The exterior paint is also holding up well, with minimal stone chips.
What volume of air is required from the compressor?I use air compressor with the attach picture air gun. Other picture is of another manual spray bottle. I honestly could see this working for non commerical applications. This product doesn't rinse off unless you use some kinda of degreeser. Pressure washer it's self, doesn't take it off. That's why I consider this product. The best. Dries like a wax.
I bought a regulator that attached to end of sprayer. If I remember I run around 60 Psi
I put on heavy, so I usually tell customer they can go 2 years. Let them decide if they want it yearly. This product is not like fluid film, that water washes off. Pressure washer wont take off unless you use a degreaser.
As a former Buffalo resident living in VA, I'd take the tornadoes any day.. you can keep the rust and dirty snow!
