It doesn't appear to have a pattern, almost like the hood was open when it happened.
Have you scraped at it?
Has it penetrated or is it on the surface?
I think a little alum etching would look nice (like sand blasted) if it were controllable
(though it will eat paint?)
Is that the same stuff on oil filler neck?
luck,greg

it looks like blue devil engine sealant after it has been put in the cooling system but comes out spraying. It is a liguid glass like substance that sticks very well. Have you or a prior owner used blue devil or similar product in the cooling system? It is alright, you are among friends.......Phil
