Lubricating poly bushes

[Omerta]

Recommended or not, and if so what with? I've done some googling and found arguments each way, and one article that suggested lubricating every fitting except ARBs.

The vehicle is a Cerbera that is being rebuilt as a road legal competition car with PowerFlex poly bushes all round. I don't want to be hearing squeaks on every bump...

Cheers
