the seize or not once was a holy war for square tapir users.

no seize folk used too much or not enough torque...an indiscriminate slobish lot having oxy torch on hand...available at SEARS for $50.....

both a film of aluminum never seize and copper coat..the auto preference...work with 100pounds of tapir torque....examine and file for burrs, ridges.

Shimano has apparently done a world class job with the BB...not doing so would become an immense PITA
