Au contraire Matey, you do indeed want to use copper antisieze.
Here is the advice fom INOX UK
Why is it really that important to use copper anti seize and not something else?
When stainless steel is fastened ‘dry’ into Aluminium, galvanic corrosion can occur as the result of two different materials at opposite ends of the ‘metal nobility’ table being interfaced. In practical terms this means that alloy crankcases can oxidise around the fastener area very quickly. Copper based anti seize provides a third metal as the ‘sandwich’ and, as copper is placed in the centre of the ‘metal nobility’ table, it prevents Galvanic corrosion. Ordinary grease or oil will not work as they do not contain the vital element. UNDER NO CIRCUMSTANCES use Aluminium grease of any sort - including aerosols - as it will probably seriously damage the castings.
