Help me get this junk off my paint

[Patek14]

A few years ago I drove through what I think was white house paint. I now want to get it off my car but I dont know how. Thoughts?



Obv washing and claying doesn`t work. Isopropyl alcohol and the risky acetone don`t work either.

If acetone wont take it out the next step is wet sanding.
