Living in Michigan we enjoy the lovely salted roads every winter, I've found the best protection is a good undercoating, I bought our jeep 6 years ago with minimal rust (think it came from out of state or was driven very little in the winter) wire brushed the whole frame and coated it with por15 paint, just touched it up again this year so I should be good for another 5 years or so

How do you apply POR15?

You know, just a regular garden hose sprinkler would work. Either the rotating head kind, or the oscillating kinds. Just move them around under the vehicle every 10 or 15 minutes to get everywhere.

Use one of those "soaker" hoses; the ones with hundreds of holes in them.

Lay it out in rows on the ground, park vehicle over it, turn on water, grab a beer and watch "the game."

My 08 GMC is starting to rust under the doors. That multi layer rubber gasket designed to make the vehicle quiet traps all manner of crap! It's hard to clean. You must do it with the door open and I usually put a sheet of plywood in the way to keep from blasting the inside of the vehicle.

You guys mentioned sprinklers and I thought of something. But BHD has stolen my thinder and idea. I remembered I have one of those HP floor washers with the spinning nozzel. I had the same thought. Put it updise down on a dolley and with the vehicle parked on a nice smooth surface, roll the thing around underneith. I will try that.

How do you guys clean the inside of your fender wells? I tried one of those J extension wands for doing your gutters but it is too unstable. Maybe one needs a gun/wand just for that with a good bend in the end.

Yes, I have a J extension that is attached with one of these:

I tighten it up fairly tight by hand and it holds the extension in a fixed position. I can see a QC style connector allowing it to swivel willy-nilly. It has a QC on the output end which is nice because I can change the nozzles to get the best spray pattern. I prefer the zero angle one for wheel wells.

A friend who is the local Rust Check dealer has seen vehicles cleaned by just the use of an ordinary water sprinkler underneath them on tap pressure and says it does a good job of cleaning. I expect it has to be moved around a bit to get to get the spray at everything. The only thing is, rust also starts from the inside of panels and that's where it's difficult or downright impossible to wash clean. Some auto manufactures could design their vehicles to be a lot less susceptible to rusting even with the same materials used and they could also make them a lot easier to clean to prevent the accumulation of mud.

Karcher makes one. Probably NAINA. Should be easy to duplicate though

I like the ramp idea on this one, but its would be much more expensive to build and it requires a ton of water flow, some 300gpm.

Thought about this myself and wondered if a pipe with a few nozzles on a small truck with a simple set of rollers would work. Maybe 3-4' wide. It would need a long handle to push it under the car (and feed water). Park the car. Hook up the pressure washer to it, then run it back and forth under the car a few times from the front and the back. Pressure should be low with several nozzles on it so it shouldn't destroy stuff.

I used to have a car wash, these folks have everyting you would ever need. If you took a piece of 3/4" pipe 6' wide and plumed up a quick connect at one end that fit your pres. washer and capped the other end, ordered 6-8 spray nozzels and drilled & tap the pipe every 8" or so….. You'd need to make a set of "legs" for the pipe so that it stayed vertical.
I made a floor washer about 3' wide this way ( with rollers & a handle) but the same idea. I'm sure that if you came up with some sch. 80 pvc pipe, that would work as well. It's a hard battle fighting that salt, unfortunatly more of a loosing battle. That mist coming off the wheels gets to places a normal "undercarrage" spray can not.
