Inquiry (采购产品): What is the blue coating? Hello, Perhaps someone could help me? …I have an insatiable curiosity going. I need some help that should be right in your “wheel-house”. In the automotive world, many after-market headlight bulbs are sold with some type of “blue coating” on the glass. I would like to know: 1. What is the blue coating? (I suspect some form of plastic) 2. How can one safely dissolve the coating off the glass bulbs without damaging the quartz glass surface? What product can I use to accomplish this? Perhaps someone who has some manufacturing knowledge in this area could assist me? Thanks a million.
