More and more glass is encapsulated glass with
rubber molded around the outside perimeter of
the glass. This can add another challenge to
glass removal since the metal can get hot and
damage the rubber encapsulation.
have found a method that has met this challenge.
The secret is in a thermal protective gel called
Cold Shield. When
this product is sprayed on the metal where the
rubber encapsulation is touching, two things are
First, it absorbs the heat for the period of
time that the pinch weld is heating to the
release point. Second, it provides a visual
temperature monitor while someone is removing
the glass. If the gel begins to bubble, it’s
time to get the Glass Blaster head moving
further around the glass.
The gel bubbling tells me the metal is hot
enough to release the urethane without the
"after the fact" oops moment.
If necessary, I will add more gel to the painted
surface adjacent the encapsulation allowing
additional time to apply additional heat to
release the bond. The main objective is to be
able to visualize the temperature of the metal
by seeing wet gel next to the rubber
As long as I see wet gel, I know there is no
risk of overheating the metal thereby melting
the rubber touching the metal. That is the main
key to eliminating any risk of damage to the
Encapsulated glass is expensive glass to replace
with OEM glass. That is why it is so important
to get the used glass out with accuracy and
