depends on what the surface is,.... cast iron or cast ally.....

but for a product that is good on both and helps to protect try thr Liberon range........

Always used a PTFE spray, but I've just ordered a can of that magic stuff from Axminster, so you'd better not be lying

Thats the stuff i use!!!!!!!!!!!

The only problem of having any waxes or sprays is that I've found that they can impregnate part of the timbers with the substance and it's only noticeable once you try and apply a finish which then doesn't take.

A tip someone mentioned years ago is proper baby talc very lightly dusted on the in/out feeds, saw tables etc and works really well. The only thing to check was that it was proper talc and not starch based talc which should be on the side ot the bottle/jar.

Actually, I'll try that. I've got a hundredweight of old candle stubs around the workshop because I keep forgetting to take one along to lubricate sash windows and end up buying another bloody box.

I've got a load of beeswax around too, but god knows why I bought that.
