The plugs just look carbonized, but are intact. No metal chunks or ceramic missing or found. I'll try the grease, though. Question: I have silicon grease, but I've only used it to lubricate the caliper on the front brake of my motorcycle. Is it good for electronics too? Or are we talking about different stuff?
