If we can come up with materials like carbon fiber, wrinkle resistant clothes, or even stain repellant clothes, why can't we come up with a material that keeps cars clean and bird-poop repellant?
there are materials out there that protect and seal paint finishes. Some of them make it really easy to wipe off dried bug guts and bird poo. Check with a local detail shop. It runs about $300. To have it put on.
