Be careful in the use of silicone containing compounds. Two very 
important things to keep in mind are that if you use silicone anywhere 
near something you will paint it can cause tremendous contamination 
problems meaning "fish eyes". In the shop I had we used a spray on the 
TIG welders to keep the spatter from sticking inside the shields. That 
spray contaminated the paint room over 200 feet away. We had to 
convert to an non-silicone anti-spatter spray to finally eliminate the 
problem. The other thing to watch out for is some silicone compounds 
can contaminate and destroy the O2 sensor on the car. There have been 
cases of silicone containing compounds getting into the air intake and 
wiping out the O2 sensor. Using the wrong (not sensor safe) silicone 
sealer is also known to kill O2 sensors. Silicone also has a property 
known as "creep". It tends to migrate. It can get into switches and 
insulate the contacts. A few years back the telephone companies used 
silicone to lubricate the mechanical switches in their phone 
exchanges. The silicone crept into the contacts and caused erratic 
operation, it took hours and hours to mechanically clean out the 
silicone.
