Dripless undercoat?

[McFlash]

I was on Craig's List and found an interesting post for dripless undercoating. I'm looking for opinions on whether this might be a good idea to protect my rust prone machine. Here's a portion of the post:

"The product I use is a lanolin or "wool wax" base so it is all natural and uses no toxic chemicals. It is a liquid that is applied via pneumatic spray gun, no runs or drips, never hardens, chips. It never "dries" so you never have to worry about water and salt getting behind it. The liquid quality allows it to creep into all the nooks and crannies right where all the water and road salt/calcium chloride gets at and eat away at the body."

What do you think?

I get all three of our cars undercoated every fall using http://www.krown.com/ and since my first car (80's Hyundai Pony) I have never had any issues with rust. The day after I bought Fiona that was what we did. They offer drip-less at other places as well yet I do not mind parking on the street for a day or two while mine drips I am sure they both offer the same benefits.
