There was some discussion about the modern sparkplugs not working or not lasting long. I read the explanation given at Green Spark Plugs web site. They think the problem is that new type plugs are not glazed on the internal insulator so then a rich mixture can make them short out by coating the ceramic with crud. I ask: Why can't WE coat the insulator with a 'glaze paint' used by ceramic hobbyists and kiln it on? Would it 'kiln' in the engine? I doubt it. Maybe a friendly Ceramicist will bake us a batch to try out. Replies are solicited.
