There's also the Law of Maximum Obstruction, which says that for
any contiguous group of cars, the probability of any individual car
in that group failing to function increases in direct proportion
to the number of other, functioning vehicles that cannot get past
it. I first learned this when I was working on the brakes on my
car, which was parked in such a way as to block Kim's car. At
one point I realized that I had reached a point where I could not
continue without a Special Tool, and I couldn't reassemble the car
until I finished the part of the task I'd started. There sat Kim's
car, wedged in by mine, shaking its head and clucking its tongue at
me for being so foolish. Since the front of the car was up in the
air with the wheels off and the hubs partially disassembled, I
couldn't even roll it back out of the way.
So I did what any SOL worth his or her Castrol would have done. I
fired up the bench grinder and modified a tool to finish the job.
And of course, no one has brought up the group I.Q. measurement algorithm
yet; it's fairly well known -- take the lowest I.Q. in the group, then
divide by the number of individuals. This gives the group's collective I.Q.
Useful to explain why a job that should take one person four hours to
complete will take four people sixteen hours (not to mention sixteen
times as much beer) and produce sixteen times as many errors.
If a sporting event involving balls or sticks is involved, divide by the
square of the number of individuals; if voting is involved, divide by the
cube.

Interesting. I've painted cars with standard sprayers, and have test shot
an accuspray, with just the opposite observations. The accuspray makes very
little overspray, and is supposed to put something like 80% of the paint on
the car, as opposed to about 30% for standard guns. (That alone can save a
lot of $$, and mess) The accu- spray also seemed much easier to use, and
*harder* to make runs, as it seemed to have much more even coating. We were
able to do something like 30-40 passes before the paint would sag! With a
standard gun, this might happen in 3-5 or so. It was adjustable from large
to small area, allowing it to be used for touch-up work.

I am also hoping to be able to use one of the regulator/compressed air
setups with my compresser, which may or may not have just enough flow.
>From anyone I've talked to, most HVLP setups are pretty terrible, and many
are just conversions of standard guns. After testing an AccuSpray, the
lower observed levels of paint in the air, and potential of smooth paint
jobs with less shop coverage has me wanting one. Most of the shops areoud
here still use siphon guns, or have been put off by other no-good brands.
Anyone else have reccommendations, experience, etc.?
