Road oils kicked up by rainwater and splashed on the undercoating by the tire seems to be the culprit. Oil dissolves asphalt.
I reach inside the wheelwell and my fingers come off with tacky, greasy asphalt stains. This was not the case after the first day or even week.
I think I'll look to some other kind of paint for the remaining three wheelwells. Bedliner compound is promising. So is a thin coat of brush-applied satin black Rustoleum. Rustoleum is an old fashioned alkyd enamel. Alkyds adhere well to clean surfaces. Easy to renew with a brush; no masking needed.
Tire cleaners like Westley's are strong enough to degrade an asphalt based undercoating, making it oily/dirty like in my case.
Other than this soiling of the body paint, which washes off easily, I've no complaint
about undercoating. Am surprised it's giving me trouble. My bad luck alone, I hope! 
to reiterate:
===undercoatings of this kind are asphalt. asphalt is tar.
oil on asphalt dissolves the asphalt to a more or less permanently sticky goo.
roadway oils degrade the coating to an extent equal to the exposure.
after running around for a while in hurricane soaked streets my coating is sticky and staining in the area where water gets thrown off the wheel onto the coating. Some small amount of this oil/tar washes off and leaves a grime on the paint. easy to wash off but who wants it? YOUR results will vary. Maybe you won't have a BIT of this minor trouble I experienced. I never heard of it before. Maybe I am a fluke example. Someone please chime in yay or nay to asphalt undercoatings... because I just put a lot of worry into young heads.
sorry about this downer.

the solubility of asphalts
Yes Hornet, asphalt dissolves even faster in petroleum solvents. I could tell y'all more about asphalt. I am a bore though! Just this much: Henry's famed Model T was -painted- with a black varnish based upon a very special grade of fossilized asphaltum. It was a remarkably black and perfectly glossy paint (varnish really).
I can pretty safely say that I am the only living man who has recreated that old time varnish from the raw materials and painted a car with the original and blackest of all black paints.
Henry's paint....
(CUT!!!! you are borrrring the crew, Sci!!!)
Hornet gets me off on tangets. Matt, thanks again for a most helpufl thread. I wish I'd had this thread a month ago.
I will UNDO my gooey wheelwell with lots of mineral spirits and a paint brush and ooohhhh what a mess that will be. Dang.

As long as Matt does not mind.. it seems his thread is making every one TINGLE with smilies
OK, no, Henry's paint did not last so long. The gloss would go down in a matter of a few months.
In essence it is like this:
-Japan Black-
Gilsonite (the most ancient of asphalt strata, from Utah and Colorado) cooked into linseed oil at high temperature with lead mono-oxide as a primary drier (lead aids polymerzation). Add solvent turps when cooled, add other metallic driers. Flow onto body panels with a hose feed (not spray!). Allow to drain. OR dip small parts in a bucket of the varnish. Allow to air dry. BAKE for a porcelain hard finish. Bake at 400F for an hour. Recoat (no roughing up needed). Bake again. Get four coats on.
The result is a black mirror finish. Elemental carbon in the Gisonite asphaltum makes the perfect black. This paint is nearly proof against any sort of paint remover other than -lye-. Even then, the way it comes off is by lye un-doing the linseed oil component of the varnish.
Do not wash Henry's paint with any sort of petroleum solvent, though. That ruins the gloss by leaching out the asphalt component.
and there you are: History in a nutshell. Or case, as my case may be

Yes, do that Matt. Just point out the downside of asphalt undercoatings.
I rubbed my finger inside the wheelwell yesterday where the tire slings water. The stuff again stained my finger with tacky goo.
