Here are some silicone grease that I have. I use the high vacuum grease to stiffen the mode ring on a Sunwayman V11R. I mostly use the Superlube on flashlight O-rings because its in a tube and easy to direct where I want it. I will use the other silicone grease on other things as needed. For threads, I probably would just use one of the jars and dab with my finger.
