Although I have never found an affordable way to prove this>> It has been done! - I once knew a company that made built-up fiberglass parts in moulds. They began having an unacceptable parts failure rate and though it might be a silicone mold release used in another part of the building contaminating the parts. They put an invisible dye into the silicone that glowed bright purple when exposed to ultraviolet light. A week later, at night, they shut the lights off and went around seeing what "glowed". Darn near everything that workers touched, glowed. It was found that a little on a workers hands was carried and deposited on everything he touched, which was picked up by others and deposited elsewhere, etc. Silicone residue was everywhere, and everywhere where it was not supposed to be, and in the recently made bad parts. They did a major washdown of surfaces, bought some new equipment to replace contaminated, and stopped using the silicone. The parts failures stopped. I have also wondered just how well can one glue parts back together that have been "lubricated" with silicone. I don't think they glue very well at all. Bill Simon Phoenix
