the last bit im on about the copper sulfate grease, is this copper slip

Before fitting the new MINISPARES flywheel, careful examination of the crankshaft taper for burrs
and pitting is required as this could cause incorrect seating of the flywheel, which would
lead to the two parts friction welding together at high RPM and irreversible damage to the
crankshaft and flywheel.
A fine valve lapping paste should be used to ensure the two tapers fit together as near perfect
as possible, this can be confirmed by an even grey finish over the whole taper. The paste should
then be washed off thoroughly and copper sulphate grease applied before the final assembly.

I have never heard of using any sort of grease on the flywheel taper?

Certainly lapping the tapers in is standard practise, but I have always fitted the flywheel ensuring the tapers were both spotlessly clean.

do i need to re-lap after taking off the flywheel and later refitting it to the same crank?

or will just cleaning the tapers be suffice?

it goes a long way to help prevent fretting

Fretting is the result of movement and destroys cranks!

good idea you could set up a target in front of the car then rev the car and see how far through the target the flywheel goes...along with what ever it takes out of the engine bay with it lmao :):):):):) could be a new olympic sport............Tom has deffo ansered this one for you... i also follow his rule.
