Paint hazy after coolant spill

Long story short, I got coolant on my hood and now the paint is hazy and rough. This is original 1974 E5 red paint. Immediately after the spill I washed the car and applied Meguiar's cleaner wax. That helped temporarily, but over the following weeks it clouded over again. Should I try the cleaner wax again or is there something better I can do?
