You might want to read the FAQ's on the WD-40 web site (WD-40 Lubricates, Cleans, Protects, Penetrates & Displaces Moisture) to be better informed (it's safe on paint and great for removing bugs). They won't say what the ingredients are that make up WD-40 but I've heard it's based on fish oil.
Gee, according to Wikipedia the fish oil theory is an urban legend :ah: My bad.
