Ok a good question for you

I live in Pa and i hear its pretty much just located in this region..My mother -in-law has a white nissian sentra that the front end is covered in Artillery fungus it basically looks like black little raised bumps that are reluctant to just about anything that i can figure..ive used the flex with the orange and white pads/cleaners, bug and tar, the green all purpose cleaner.. i was wondering if anyone for this area has had this problem? And if so were you able to clean it off? thanks Tim

If you google "removing artillery fungus from car" you will get several suggestions.  Some I would try, others I wouldn't.  One that I would suggest trying is white vinegar.  But I would wash the car right after doing this process as well.  And then complete the process with clay bar, polish, sealant and wax.

I'm from pa too but never had that problem with the car. Had seen some on houses before. And vinegar does seem to work. Just where in pa are you Tim?

I had them on my Focus two years ago. Clay, machine polish and wax cleaned them up. I only had 20 to 30 spots on the fender and hood. I picked most off with my finger nail and used the clay to cleanup the residue. GL.
