Help on removing white overspray from exterior.

Hi all,

I just noticed this today and need some help from this community!!

About 3 weeks ago, I parked next to a fence being painted on a windy day. The guys doing it were using a spray gun and I thought I was far enough away but the wind carried over to the passenger side of my truck. It comes off when I scrape it pretty hard with my finger nail and a wet towel.

What’s the best way to remove these white overspray spots? Is it too late?

Just curious if you all have any tips on scrapers or stuff that won’t damage the existing paint.

Thank you for your help!
