Right, just noticed a little bit of what looks like blue paint in my engine bay. Only a little bit, on top of a couple of the components. Not sure if it has always been there, but only a small amount, just me being a bit obsessive and wanting to clean it of. But I just want to find out what it is before I start trying to remove it as don't really like touching engine components unless I can help it. Anyone else have this? Kind of sky blue in colour. Sorry got no photo to show.
