2k clear coat begins to harden as soon as you press in the red button and mix the activator with the rest of the can's ingredients, so it's only good for an hour or so, then it will no longer spray. So while yes, you can use the can for more than one set of headlights, you need to do them all at once, because the clear coat has a time limit on it once you activate it.
Is that can just enough for one set of headlights?
