I know that this is an older thread, but I wanted to chime in and say that I’ve used Finish line dry lube also. It’s not actually dry, but will dry after application. I’ve always assembled and let it dry on its own for a day or three before soldering/using.
I usually use a paintbrush and pop the top of the bottle so I can dunk and apply with a small paint brush (talking watercolor, not chip brush). I wouldn’t stick my face right over the bottle, but with the paintbrush method, you don’t get much of the fumes and it applies fairly evenly.
Also, the small bottle someone else linked is more than enough for a lot of switches. I’ve done 120 on 1/3rd of a bottle and still probably had more than half of that left.
