Just wondering if silicone spray is suitable to use on cases for resizing?

No, but STP works quite well.

Thanks

1 part lanolin to 2 parts caster oil is also good.
to mix, use a double boiler.

I actually just ran out of my "One Shot' lube was looking at the tin of WD40 sitting on the shelf.
Hmm.. maybe not. I reckon WD could be problematic if not fully removed with sonic cleaning. Will dig out that imperial sizing wax and just get messy but I know it works well.
