Slowly closing in on the fun stuff. The brake assemblies all use plastic/nylon at the pivots! Well, they've lasted 30+ years. Sil-glyde for you.
I've read suggestions to grease friction shifters and suggestions to leave them dry. There's more nylon here (used as crush washers to add friction), though the lever faces directly contact metal washers on both sides. A bit of sil-glyde on those faces, and we'll see how it goes.
I planned to use marine grease for all bearings (metal on metal), but the bottom bracket has a plastic sleeve. I've yet to personally experience marine grease causing problems with plastics or rubber (after using it in a low-end coil suspension fork), but I'll probably err on the side of caution and use silicon grease here too.
