84 / c4 queston

Is the top on an 84 / c4 suppose to have any weather
stripping attached to the bottom front edge ?
the reason I ask is that I just had two windshields
installed. The second was the result of some advice that Dad
gave me here on this group about the installation procedure.
even after the second installation,
the top seems to bow just a tiny bit in the middle along the
front.
this is allowing water/wind to enter the car.

any advice would truly be appreciated.
thanks

Having a hard time trying to figure out where you put the second
windshield. :-)
On a serious note, both tops on my '90 have weather striping on the
leading edge where the top mates to the windshield support.
Looks like they would easily seal the top even if the gap/bow in the
middle was not much larger than 1/8 inch or so.
Perhaps something is not quite right with the removable top securing
bolts or the seats they reside in?

Good luck!

Tom is right on, there is a seal on the front of the top and the top of the
windshield on the newer tops. If the installer followed the same procedure
putting the second windshield in it could also be installed wrong. The new
sealers, not the 80s rope type, can and will let the class sink in to far
without blocking its travel until it sets. On a nice warm day it can sink to
where the top seal can't stand high enough to completely contact the outer
corners of the top. Then if the top is pulled down to contact the corners it is
bowed up in the middle. During the glass installation the installer needs to be
able to fit the windshield retainers and seals to the contour of the existing
top. When my installer was aware of what had happened he was able to hit the
second windshield right on and it sealed like new. I kept the retainers on for a
full day before removing them allowing the sealer enough time to set as an extra
precaution.

yea, I am keeping the two windshields a secret :-)
my 84 has only one top. it fastens in four places, one on
each front corner and
two across the back. I really don't see how it could be put
on incorrectly.
the top of the windshield has weather stripping.
I was just thinking that maybe I am missing a weather
stripping along the front of the top
or if putting some type weather stripping on the top would
help fix the problem.

thanks for your response TomC
g'day to ya

Dad,
was Tom talking about two different tops ? my 84 has only
one top.
Does my single top require a seal attached to the top itself
?
it didn't have one when I bought the car.
I followed your earlier advice and told them about the extra
required sealant.
that's the reason they re-done the windshield. they added
the required sealant but I still have the air/water leak
coming in from the center. the front corners seem to be
fitting and sealing ok.
(not sure if they let it set completely before putting the
top on)

thanks for your continued help with this Dad.

Can you move your clamping points together on the top and/or apart on the frame,
(don't remember them being movable)? If so try putting some soft but rigid
material under each outer corner, (maybe about 3/8" X 1" X 2"), and latch it and
see if it takes out some of the leakage.

they are not movable. they also don't latch.
top is held on by four screws / two on front edge and two on
back of top.
when the front corners are bolted down that are bottomed out
and seem to fit fine on the corners but the muddle is then
bowed up just a little too much.
do you think that a thin weather strip added to the middle
third of the tops front would help ?

thanks again for sharing your knowledge Dad

I guess I'm rejecting the top bowing in the middle and still think the corners
are to low. You are talking about a convertible aren't you, or was that the
original post? The screw down corners don't sound right. Let me know and I'll
look at one this afternoon. They are having a Sam Hornish day with a parade and
a ton of Corvettes that I can check out.

'Key:
My car has two tops, one bronze tinted clear glass and one solid
fiberglass top painted to match the body.

Mine use the 4 torx head bolts to mount to the roof, two mounted
vertically in front underneath the sun visors and two in the back
oriented horizontally.
I don't know if mine leaks water as it's never been, and probably never
will be driven in the rain.
I've never noticed any air noise coming from the windshield area, even
at Warp 125. Someday, I'll find a LONG stretch of road and I'll let you
know if there's wind noise at Warp 180+. 8-)

No its not a convertible.
its a one piece hard top like the one on this link.
