Ron Ketcham- Isn't the AI/VG undercoating asphalt-based or something like that?
What color is it when it dries?

Most solvent containingl undercoating contain some asphalt, it depends on wether they use left over or what is referred to as "cut-back", a much more highly refined version, and then combine it with some of the wax based rust inhibitor. These are black in color.
They do make a water based, which can be black or clear and meets most of the specs. Not as good for rock chip protection in my opinion though.

Ah, OK, thanks.

I was under the impression that electronic rust proofing modules work really well at prevention rust? I know a company that has been using them for years and has zero claims with them. I wonder if the technology behind them has improved?
Here's a great article about the infamous Undercarriage Washer: http://www.autopia.org/forum/topic/128250-undercarriage-washer-attachment/

Works on boats and bridges, IF there is a sacrifical iode. Check around a bit more, like the state of Penn. and what they did to dealer and the companies selling them, David. (it was a several million dollar fine, etc)
Take one that they sell for cars and take it apart, you'll see what I mean, just wires attached to blinking lights.
You may know a company that was satisfied, but the real numbers that the states, and the car companies have, say something completely different--"They do nothing, do not work on an auto or truck."

NY uses a little bit of everything mentioned in this post.
Never had a problem with the usual wash & wax. Nowadays I use ONR, so first it's a trip up the road to the coin-op wash to use the high pressure rinse, then it's back to the heated garage to clean with ONR and then polish & seal.
In April or May I use a garden sprinkler to rinse the undercarriage. 7 years and 100,000 miles and you'd think the car was garaged in the winter.

I would use Auto Finesse Avalanche in the pressure washer, as this soap is designed for winter crud removal and go with a good sealant or a coating. Sonax PNS is a good sealant with great sheeting properties and it comes in aerosol so you can get it those hard to reach areas. Adams also make a aerosol spray sealant. I live in NYC and right now my DD's are wearing DG501/601 topped with D156. In the winter they get a spray wax after every wash. Coatings would be the best way to go.
