Hi, we've just put up our folding shower screen & we need to get some "Silicone Lubricant" for round the glass & joints. There was a tiny packet of it in with the screen but we can't find tubes/tubs of it for sale. It was about the consistency of vaseline & doesn't set at all. Would it be under a different name does anyone know? We were wondering about using the permanently flexible type at first but we don't really think it's suitable. Please has anyone got any info? Thanks very much.
