| So Joe, was
it really zero degrees?
Yes it sure felt like it was! I normally
use a temperature and humidity gauge when I do installs for any Ford tests, but
unfortunately they don't read down that low. So I will take their word for it.
To start with, how tough is it to
cut the windshield out when it's that cold?
Well actually, I removed the windshield a
couple of days earlier under "normal" conditions, but didn't strip it down until
the test day when the car was 'cooled' down in their special cold chamber.
Then you primed the pinchweld in
the cold?
Yes. In the cold I stripped down the old
urethane, and applied the U-413 pinchweld primer. Using a heat gun, the primer was dried
(what they call flashing).
And how was the urethane applied?
The windshield was prepped and primed
outside of the cold room. But the urethane was put on the glass inside the zero degree
chamber. Then it was installed. Oh, and of course the crash dummies were inside the car
the entire time.
How long did you let the urethane
set up before they crashed it?
After it was set, a couple hair dryers
were used to warm the urethane for fifteen minutes. Then the tow truck came and way
it went to the barrier. It was one hour from the time it was set until the time it
was crashed.
Did you get to see the crash test
and what happened?
Yeah, from about a hundred feet away. It
got mangled up pretty good. At first one of the guys said "it didn't hold!",
that the sides let loose. But when I went up to it right after the crash, it was just the
sides of the wrap-around molding that had came out. But the glass was all intact.
Pretty awesome, huh?
No kidding! The hood was all crumpled and
got shoved hard against the lower part of the windshield. And the passenger side air bag
really did a number on the glass, but it didn't budge.
Go ahead and forget modesty. Do
you think that the installer (being you) had some bearing on the success of the test?
Well, well. Let me answer it this way. I
normally apply the sealant to the pinchweld, but for this test Essex wanted it put on the
glass. It is a chore to make sure that the bead gets in the right spot so as to line up
with the old urethane on the pinchweld. If it's off, it can make a big difference.
Do you know any details of the
other manufacturers tests?
No, not really. I heard that one of them
almost passed, but that the passenger side air bag blew the 'shield right out when it
deployed.
So were you surprised that the
Betaseal cold test worked?
To be honest, yes. Right after the crash
I went up and stuck my screwdriver under the windshield. The urethane was still 'gooey'. |
