waste of time.  just another way for garages to make money off of the
unknowing and the gullible.

Don't walk, but run away from this $$ making scam. (It's about as
legit as a 'doc fee').

1, Most every vehicle has at least a 7-10 year 100,000+ mile
corrossion warranty in place now. Especially if it was made since the
mid-90's or newer. Some have even longer than that.

2, In a great many cases you will void the original corrssion warranty
by adding this crap.

3, Adding extra weight is not exactly a positive thing for handling or
economy, however much extra weight it may be.

4, Many of the spray in jobs end up coating over things that they
shouldn't due to the careless nature of the $6 an hour guy that sprays
it on there. I have seen this a few times, especially when they get
bored and spray things like suspension adjustments!

5, It's often the case that this stuff seals IN the moisture and junk
that is already accumulated and can actually cause corrossion to come
faster. This I have seen a few times.

6, In a great many cases they charge you the full fee, hand you some
worthless paperwork (by the time you need to make a claim the company
has changed names 3x or gone out of business entirely so you have a
worthless piece of paper), and worse yet, don't even spray the crap on
you paid for.

Other things that fall into this line include:

Pin striping for $80-150 (the average stripe service charges $12-20 a
car depending on complexity and if they can't pinstripe a standard car
in under 90 seconds they are friggen slow.  You can do it yourself or
frankly if they want to keep the stripes on there don't pay past the
$20 they paid for them.

Secure Etch (otherwise known as Glass Etch).  Before you bother paying
some rediculous multi-hundred dollar fee for this 'service' call your
insurance company and see if they give you a legit break on your
comprehensive. Odds are they don't.  In either case, this is another
one of the scam things that tend to change the company name every 2-3
years to avoid actually paying out a claim.  If they DO pay out a
claim it will usually be nothing more than covering your deductible.
Save the money... you'll end up paying it anyhow.

Doc Fee's.  Every dealership seems to want to add them. They also love
to give you the absolute BS phrase "We have to put it on there by law.
We have to charge everyone!"  There is not a single law written in any
of the US states that has this anywhere in there.  Not one. If you
believe there is, please provide at least two links to it and
Wikkapedia is NOT a valid source.  Don't pay Doc Fee's.  In this day
and age they need your sale more than you need their car.  This goes
100% to the owner of the company, not to any sort of employee or
documentation. After all, they can't sell you the car without
completing the documentation.  This, to me, is a huge slap in the
face.

Extended warranties:  Do some VERY careful homework. Only about 1 in
25 extended warranties are worth te printed paper.  Before you
actually sign for one, take the contract, while you are there in the
office, and call up to 'make a claim' and see how they intend to treat
the process. That will give you a real quick idea on whether or not to
get one.

If you do intend to get one, try to get one that is through the
manufacturer and that actually covers something.  Most have more
exclusions than coverage.  If you are not going to keep the car well
past the warranty period save your money.
