How to get concrete off paint??

Turned around in a concrete plant yard last weekend in the wifes truck. Didn't think mich about it till i washed her truck today. What i thought was just mid turned out to be concrete. Took it to careask and used the sprayer to get the thick stuff off. What i couldn't get with the sprayer on the front fender is really on there. I just soaked it with some diesel and gently rubbed it off. Took the brunt of it off. Up close you can still see the outline where it was. What could i use to get rid of the lines? Any and all help appriciated

I use acid diluted 50/50 for tough stains on my vehicles, just make sure to not get it on chrome or stainless for very long.

What acid are you talking about?

Concrete blaster or similar product. WD-40 will also work but needs to soak a while. I pump concrete for a living so I am more than familiar with concrete removal from vehicle and equipment

Where would I find concrete blaster? I have the concrete off the fender. Am looking for a better way to get it off the wheel wells.

Online, a local Zep distributor. Go back to concrete plant. Im sure they have it for their equipment
