"Silicon is a chemical element, the basic stuff of which microchips are made. Silicones are plastics and other materials containing silicon, the most commonly discussed example being silicone breast implants. Less used by the general public is “silica”: an oxide of silicon."Silicone will not hurt most cured paint job but it leaves a residue that makes future paint jobs and/or repairs somewhat difficult to accomplish without having to clean thoroughly - otherwise, problems such as fisheye can be expected.
Some paint shops will not allow any silicone products in them, because of the possible contamination of the shop.
There are non oil-based, non-silicone based lubricants, so why not use them - water-based products mentioned above or products like K-Y Jelly?
