If it hasn't gotten too much into the paint you may beable to re-clear it.
You have a black truck the hardest paint colour to fix. It is why so many company trucks are blah white it is easy to fix.
I used brake fluid to strip the paint off of a old 1980s hood on a truck I was restoring it worked good
I tried commercial paint stripper didn't work tried new brake fluid that worked but keep in mind paint used in the 1980s wasn't as hard as what is used today.
