Returned from Easter holidays and found car windows had overspray on them. No idea who did it, it was parked in driveway. Anyway their are lots of tiny clear drops which are a problem when the sun shines on them. I am sure methylene chloride paint stripper would get if off, but that is pretty nasty stuff. I got some grafitti remover, which comes in plastic bottle, so I didn't think that would be too harsh. It does seem to attack rubber, so have to mask that off. Looks like it dissolved the small drops, but wiping with rag has smeared that into a thin film. So to get rid of that, used rags soaked in acetone. I chilled the acetone in the refrigerator, so it doesn't evaporate so quickly. Has anybody found a better solvent for this? Turpentine or alcohol seem pretty useless.
 Second problem - it is also on paint. Being clear, you can't really see it, but you feel it when you run your hand over it. I doubt there is anything that will get off the over- spray without also damaging the paint. It is plain old solid white, not metallic with clear coat.

For glass, a razor scraper is quick and effective:

which will remove almost all of crud on glass.
For the remainder, or on paint, you have to know what it is.
Are you certain it's not tree sap? That's much more probable than catalyzed auto clear.

For isopropyl alcohol (which doesn't affect auto paint) get the highest concentration, usually 90% or higher is readily found.
Don't skip the thorough wash before any other action.
