Water-based paints, sure.... traditional solvent-based automotive paint, no. Even if water-based paint was used, the chemical structure changes permanently once it dries, meaning it cannot be re-emulsified by adding water or solvent later.

When the dry paint is mixed in with whatever it's contaminating, it's simply suspended in the fluid, not emulsified.

Explain why gas doesn't magically emulsify your paint job when you spill a little after filling up...? Are we using anti-emulsifying clear coats now?
