Proper reconditioning of 7018's requires significantly more heat than 300 and for more than an hour. Various manufacturers recommend anywhere from 500F to 800F for one or two hours. Does 300F for half an hour noticably improve stick performance? Almost certainly does, but for the sake of accuracy, the "proper" procedures call for significantly more heat. S/F.....Ken M
