Paul;;;;; the Silicone,,,is it Black and soft ???? It should be Urethane Black,
it can be harder under the Glass ,,,It will be unseen under the trim,,,,,,,
but some people have used silicone in the are between the Glass and Paint
It come's in Caulk tube's,,, to install with Caulk gun on the mounting flange to the windshield opening,,,,
,,and you set the Glass on it's lip, works like denture holding creme,,But Stronger.
They sell a T-handled cable asisted Knife wih bent blade to cut the urethane,,
also they sell a set of handles and a spool of twisted 6 strand fine wire/cable,
with a Ice pick needle to push the wire under the Glass,, to run the wire inside to hook up the handle with a allen set screw,,,
,,inside then you saw the urethane out from under the Glass,,,
It can be done you start on one side,,,
,,at a angle down and towards the center and saw till you get to the curves and go slow,,,,
,,,The wire gets thin if you go to fast and Breaks with out coolant,,
from a spray bottle,,,
Windex works fine.,,,,Mike
Before you start remove interior trim headliner and a Pillar's they will be scratched
,,,,,And place Masking tape on Painted surface's outside and inside on metal part of dash
,
The Glass man will do it in front of you,,, Watch everything he use's and technique,,
It will help you later when you have to do the next one,, and well worth the money for a learning curve,,,My car had been severly over Caulked or recaualked with urethane and silicone black ,
,,Bought new Clips from Clyde and Screw in replacemet pins,,
,,, Actualy you have to remove the windshield to replace the pins and some clips any way,,
,,,If some of the pins are lose try to remove them gently and if holes are clean and ''larger" making a loose fit,,
,Try a dab of 5 minute Epoxy,,,Mike

and has a picture ,,,
It's in interesting tools you made for your h-body section near this section I beleave,,Mike
