I've heard that during the 50's and 60's the BMC works rallyists always
carried a can of scouring powder in the tool kit in case of a slipping
clutch. Should the clutch begin to slip, a handful was poured into the
(added on) vent on the top of the bell housing. The theory was that the
scouring powder would roughen the surface of the flywheel and clutch
faces so that the car could have a better chance of finishing.
Don't know if the above is true, (maybe some one has the definitive
answer), but is sure sounds neat anyway.
