For me, Mother's Clay Bar (probably the only clay bar easily obtainable in the market) worked for my overspray. I had overspray all over the car... and right now, only the front bumper needs some claying. I kinda missed it during my claying session. Still, it's a good investment if you're into detailing. I suggest diluting the Mother's Showtime cleaning QD with some distilled water para massulit
If it's on the windshield, and the claybar isn't working, try acetone or lacquer thinner to soften the paint, then a clay bar or a razor to scrape the paint off - but be very careful in ensuring that you don't get any of the acetone or thinner on the car's paint, as it'll soften and degrade it.
