I was driving about 45 m.p.h. on highway
my hood has always been hard to open because of the seal I
put on it , and it poped up so fast , it was hard to see , runned
the hood and smashed the glass with the horn , the glass looked like
a spidder weeb , my new marine lins was totaled , but lucky , I
didn>t
get in a wreak , on I:5 going into Seattle. lots of traffic in the
morning. Hope Hagerty lnsurance comes through. I will get a logging
chain to keepinp it popping up . Gord Souter E mailed me about
parts glass hood $ 400.00 new steel hood $1700.00, I took it to A
good shop , they are supposed to call est . to Hagerty Mon.
The old hood sprung quit A bit ,
This car has been in storage for about 30 years ,I
think.

condition , Lagoon Blue 1964. Hope to bring it to Cleina next year
if I don:t have any more miss haps,

Ross, if you can stand more questions on the hood: Did you have the top up
and the windows closed (at least the front windows)?

Since some people have driven around without the hood latched and it hasn't
flown open, I have this half-baked theory. You may have noticed that in newer
cars (which are sealed up fairly tight), that opening or closing the front
windows when driving at speed can cause your ears to pop. The area just aft of
the windshield is a low pressure zone. So, my theory is that if the top is
down, or if the front windows are open, the interior of the car has a lower
pressure. This lower pressure transmits forward to the trunk through the heater
vents and other holes in the firewall. This may be just enough to hold the hood
down. But, with the top up and the front windows closed, the air pressure
inside the car (and under the hood) is just a little higher. This might be just
enough to allow the hood to lift more easily.

Another possible explanation for the different experiences with different
cars might be the size or condition of the hood seals. That is, if the seals
are
thick the weight of the hood alone might not close it fully. This could
leave a small crack open at the front of the hood allowing air to come in and
lift
the hood. Actually, now that I write it, this theory actually sound more
likely to me than the one I wrote above. :eek: How far forward the hood is
relative
to front of the car body might make a difference too.

Sorry, but I'm not going to experiment on my car to see if any of my ideas
are right. :) :)
