Most recently I had a case where there was a brass sleeve bearing surrounded by a wicking material of some sort, only a small hole available to add lube. Was debating between 3-n-1 or PTFE and opted for the PTFE (i think it may be the same brand you show above). IOW, no way to add a solid grease (or do people melt it first? hmm hadn't considered that).
