Hi Bb, Inox is really good for unseizing things, you can get it at Bunnings in a spray can. I have Inox and Silicon Spray on board , the silicon is for the plastics, like the Delrin sheaves in the blocks , and Inox for any metal. It's a protectant as well as lubricant, so after you've finished you can leave a film on turnbuckles and nuts/screws suchlike, it really stops your metal getting that funny corroded sheen. SB
Most lubricants( spray can ,wet penetrating types) will free up and lubricate a lock. Graphite powder may not free up a seized lock as you may be unable to get the graphite to penetrate . However, to lubricate and maintain a working lock, graphite powder is often the best choice because it is a dry lubricant and it wont attract dirt.
