He is talking about the need to lubricate the mould alignment surfaces and spru plate as directed in the instructions. You do not need to do this with an iron, steel or brass mould, but with aluminium it is essential. No biggy really and a small price to pay for the reduced weight, faster cooling and outstanding surface finish on the balls (oooh, Matron.) Just keep the cavities clean and you will be ok. I've used Lee moulds for nearly forty years and whenever I've had a problem with one it has always been resolved with a bit of wax (I use carnuba) on the alignment surfaces.
