Dirt stains under clearcoat?

[Steadfast detailing]

Doing a customer's car tomorrow and he sent me this. He accidentally went off-road in his Mazda3 and got his car all muddy and dirty. He pressure washed it off but was left with these dirt looking stains. He says it feels fairly smooth and flush with the rest of the panel. Never seen this sort of staining before and especially in such a short period of time.


When I have a look, I'll try using a clay bar first to see if its above or below surface before I move onto polishing it out.


Has anyone seen anything like this before? Thanks guys.

That's weird,to me at the bottom of the door has a look of pressure washer damage.The streak from the door handle down looks like a chemical etch.

Looks like a goner from the pic but good luck and I hope it comes out for you.

That's weird. I don't see any which in which going off road would be able to deposit dirt below the sealed up clear coat. If it feels smooth to the touch the clear coat is most likely in tact. Hit it with a light polish and see what happens.
