I should comment on silicone spray and.....anything to do with a vehicle. That silicone was a nightmare for us in the auto industry. Much of the "shine up the interior" stuff has silicone in it. We saw many failures with Cruise Control and brake electric circuits because it found its way into switches. Silicone spray used under the hood to "spiff up" a used car gave us EFI problems, ABS failures (repeat trouble codes until you just threw away everything and started over).
Unbelievable how many crazy problems were caused by "auto detailer" services. Especially the ones that come to your home or office and "detail" your car. We spent years teaching the dealers how to avoid ruining a perfectly good car/truck....and then the customer clips a coupon out of the paper and orders up a boat-load of trouble.
The worst place to have silicone spray is around anything painted. It is an amazing molecule that figures out how to creep under paint and start peeling it off. All it takes in one little pit or scratch and away it goes.
We went to BIG extremes of control in our factories to prevent bad paint jobs. Employees are not even allowed to use deodorant or hair products, because there is a little silicone there and it can get into the air and make fish-eyes in the paint. We even had to carefully cover our shoes before entering the finish booths, because many shoes have traces of silicone that was used in the molding or assembly/stitching processes.
We finally forbid our dealers to have any silicone sprays in the parts or service departments. What a nightmare....the stuff was like a virus.....it could get places we couldn't imagine and was nearly impossible to clean up.
I still hate that stuff.
