Interference powders are what is used for making these metalic paints
that shift colors when viewed from a different viewpoint or with a
changing lightsource.  They are also called mica powders.  Each
granule is a small chip of mica coated with iron oxide.  Light is
reflected off the mica chip and passes through the coating.The
thickness or number of coats of the iron ox determines what color
appears. They are most effective applied over a very dark background.
These  powders are the basis for pearlescent finishes, too. BTW the
wall treatment was for a "nightscape" effect on the walls of a home
theatre room. Happy Holidays, Bill and UUC'ers

I wasn't confused, I was questioning the relationship between a rich fuel 
mixture and a stuffed cat.  I provided an example where this doesn't happen 
and an explanation of how it can, but I don't see how an improperly reading 
O2 sensor can stuff the cat.
Gary Derian

Sorry for the confusion...
I should have typed

"If the O2 sensor VOLTAGE is low, then it reads the mixtures as lean an 
enrichens it more than it should, thus stuffing the cat..."

Gary, I know you have this long held belief that fuel cools a cat. But I 
can tell you from experience that the only time you see a cat glowing so 
red hot that it can set fire to the carpet, is when fuel is being dumped 
into it and ignites.  The cat is supposed to get hot, it's not supposed 
to have enough fuel to catch fire.

Yes, that takes oxygen too, so it's generally a misfire situation. Hard 
to get in an OBDII vehicle, as to prevent this exact scenario, OBDII 
vehicles will shut off the injectors if a misfire is detected.

I've got a 94 ford ranger than can prove this.

Subject: Quick brake rotor question - rust
Message-ID: <[EMAIL PROTECTED]>

Time permitting, I might be able to shuffle around in the garage this
weekend and install new brake pads and rotors.  Well, the pads are new, the
rotors are stock, taken off before installing track stuff.  (Going back to
stock street, due to the fact that I have a track car now, and I'm kinda
tired of having to clean brake dust off the wheels after EVERY drive {not
that I actually do it!}, and the squeaking is getting a bit annoying on the
street car.)

Anyway, about to reinstall the stock rotors, and noticed last night that
they have a very light layer of surface rust.  I know that this is to be
expected from stock iron rotors, and doesn't particularly bother me, but was
wondering if anyone had any suggestions for the best way to clean them off
before installation.  And what sort of coating, if any, to put on the hat to
prevent re-rusting (if possible).  I know that the rotors will rust up after
being driven in the wet and put away without being "squeegee'd" by braking,
so I don't care about that, but is there a way to keep rust from building up
on the surfaces not under the pad?

Thanks,

--Dennis

My opinion?  Just drive it.  Any "coating" on a brake rotor would surely be
a bad idea from a braking standpoint, and would only last until you were
through that first stop sign ... Maybe the second.  The amount of rust on a
brake rotor is trivial and it's gone after you hit the brake pedal ...
Assuming you're moving at the time.

Well, I suppose something like a TiN coating might last for a little while,
but braking performance would certainly suck.

If the rust REALLY bothers you, you might see if you can get carbon fiber
rotors like those used on F1 cars ... Might be a bit pricey though.

Thanks, Karl.  But perhaps I didn't make myself clear in my original post.
I *know* that the swept area of the rotor under the pad will be cleaned at
the first use of the brakes.  So I'm not concerned about that.  It's just
that the HATS are rather unsightly.  I don't care that much, but since I
know that most new rotors do NOT get rust on the hats when first put into
use, I was just wondering what sort of coating NEW rotors had that prevented
rust from forming instantly (on the NON-SWEPT portions of the rotor).

As it stands, I've gotten a few suggestions, from Por15 to Eastwood's metal
wash to anti-seize (LIGHT coat) to chemically "bluing it" to AluZinc to
Cosmoline to BBQ paint.  I think I'll just try a quick shot of Rustoleum
iron oxide primer.  If that doesn't work, I don't really care!  :-)  :-)

Vty,

That's Katherine Hepburn-Simpson, I believe.

"dOAh, dOAh, dOAh!"

It's terrible what the palsy did to her doh.

Homer used the inflection-free "Doh!"

It was Homer O'Leary who perfected the apostrophe-infected "D'oh!".

We're working on the Anti-Superfluous Apostrophe Taxation initiative.  We
figure for every bonehead that puts an apostrophe before every letter S,
taxed at .005¢ per incident, we can fund the war in Iraq and a manned
mission to every planet (including Pluto, whose size will be increased to
regain planetary status) within a week.

While on the subject of initiatives, the other bill we're looking to put
through is the Adjustment of Antiquated Greetings and Expresions program.
For example, Christmas.  The common greeting is "Merry Christmas", as many
of us have heard.  Studies have shown that the word "merry" itself is no
longer considered modern English, with a JH study showing that 99.85% of
usage is confined to the period between December 9th and December 25th, all
relating to the holiday.  The remaining .15% of usage through the year is
strictly among holiday music vendors discussing next year's catalog and
listing the names of Christmas songs.  Besides that, the word "merry" has
not been commonly used since July 14th, 1854.  Alternate-use dispensation
for the Christmas greeting will be given to "Punctual" ("Have a Punctual
Christmas!" is useful for subtly reminding relatives not to be late),
"Generous", "Sober", "Amicable", and the general purpose "Good".

Expressions targeted in the AAG&E program include such examples as
"bitchin'" (come on, Californians, 1982 was a long time ago, get with the
program), "wicked" (you too, people from Massachusetts), and "phat" (believe
it or not, there are still some pockets of resistance).  Increased penalties
for "mine's" (instead of "mine") and "Me and him..." include mandatory
sterilization at the first offense, laryngectomy on the second.

So to, all, have a Perfunctory Christmas, an Unambiguous Kwanza, a Passable
Hanukkah, a Circumspect Festivus, and try not to have a feculent New Year!

Subject: E34 M50 Emissions
Message-ID: <[EMAIL PROTECTED]>

It was bound to happen sooner or later.  My '95 E34 525i failed an
emissions test.  I live in MD and we have a treadmill test.  I'm
trying to track down the problem and need some pointers on where to
start.  Here are the results.

HC    State Standards - .9 GPM  Inspection Readings - 1.6 GPM Failed
CO    State Standards - 20.00 GPM  Inspection Readings - 43.34 GPM Failed

As you can see, it failed pretty bad.  The car has 132k miles with no
drivability issues that I know of (wife drives it daily).  I did the
stomp test looking for codes and got none.  As I understand it, the
high HC is an indicator of unburnt fuel.

So what is the first thing I should check for?  Intake leaks?  O2
sensor?  Coolant temp sensor?  I hoping the cat is OK and it is fairly
simple to track down.

Thanks for any help.
