In such discussions where the two opposing views appear to be the "science" group vs the "I've been doing it for years and it's never been a problem for me" group, I tend to side with the "science" group. That said, I did have a rear wheel bolt seize on my MotorSport, and broke two T25 (I think that's the size) bits before having to drill it out so, on this occasion I'm on the add ant-seize side.
