Yes, this is excellent advice. I keep a bottle of Meguiar's Quick Detailer and a microfiber cloth in the trunk. The birds at my office sometimes use my car as target practice.

That said, you can get crazing even if you're meticulous about cleaning off the contaminants. Sometimes it's a factory flaw that takes awhile to manifest.

Hey OP, one alternative to repainting is to find a rear-ended car in a salvage yard and buy the hood.
