I make some items from card, which have moving parts, i.e. one piece of card slides over another piece of card. To lubricate the moving pieces of card I use candle wax.
Does anyone know of a better lubricant than candle wax, one that is more slippy, lasts longer, and does not mark the card? The use of candle wax goes back many scores of years, and I thought that there is likely to be a modern replacement that is an improvement, if only I knew what it was.
