I've been getting a lot of orange/brown spots on my paint, that are near impossible to remove. I can't tell if it's tree sap or bug stuff or what...most spots are very small, about the size of a pin head or smaller. Clay bar won't remove it, 303 Aero won't remove it, compound won't remove it. I can ocassionally remove them with my finger nail, but not always. I clay bar often removes most of it but won't finish it off.

Any help with this? EVERY horizontal surface on my car looks like hell.

 

it sounds like rail dust. Do you park anywhere near railroad tracks?

Get some IronX.

It's not rust. It's either sap or something from bugs. I Park near a few trees.

 

I think I know what you're talking about, I get the same little spots on my car but they always come off with a fingernail.

 

I wonder if is artillery fungus...
