Green Spot on Clear Coated Panel.

I found this green spot in front of the BR window on the right side of our trailer. I have tried everything from mild cleaning solution to polish and a medium cut abrasive to get rid of it but nothing is having any affect and I do not want to cut into the clear coat any further. Has anyone seen such a stain before and have any ideas how to remove it? It looks like it may actually be in the aluminum beneath the clear coat.
A dime would just cover the spot and it is not a huge problem but I would like to know what it is.

Green Spot

Thanks
Kevin

Green Spot on Clear Coated Panel.

I have no idea what might have caused that, but judging by the picture it seems like that it is in the metal and not the clear...

Maybe a good place for a decal?

I might speculate that the aluminum in that spot might have suffered some chemical contamination prior to being clear coated that has since become active?

The only other thing I can think of that might cause that is the metal being made hot by an electrical short or arc against the skin. (Inside the wall)

I would more likely think my first guess than my second guess.

I think that you are correct, this green stain is not on the surface and was likely created from a flaw or impurity of some sort. Its not a big deal but would be nice to clean it up. I do not believe I have an electrical problem.

Thanks for the responses.
Kevin

I have had spots like that, it is aluminum alloy corrosion. Easy enough to remove with a pencil eraser. Only a temp fix, it comes back.
