Hi, I have encountered a number of frozen screws/bolts on my (cro-mo frame) bike - so far, the list includes the BB, the (threaded fork) expander bolt in the stem, a brake boss allen bolt and right now, a hardened steel screw that's stuck in my rear pannier mount.
Does anyone have any advice on how to prevent this kind of problem in future? Should I just use liberal quantities of grease? I was just going to purchase of tub of general-purpose car grease, would this suffice or should I get anything more targeted at bikes? Perhaps I should use different types of screws?

In my experience, grease usually works fine. There are available anti-sieze compounds as well - I'm sure others will weigh in with details on those. Best of luck.

I've been using wheel bearing grease for years. It works just fine. I like the little 99c plastic packs that are usually kept on a counter display. Buy a tub if you want enough to leave in your will to your great grandkids. If you're fancy, get some Phil Woods bike grease. It smells nice.

Okay, here's one of those weighing in. I've had a small can of anti-seizing compound (generic NAPA product, not Never-Seez) laying around the garage for years. I've never used it on a bike part. Plain old automotive wheel bearing grease seems to do the trick. I've never had a problem loosening a fastener I've assembled with grease on the threads. Also applies to aluminum seatposts in steel seat tubes.

Get some anti-seize from your local discount auto parts store and use it on all of your fasteners. It is grease with some other stuff added. It works well. The one drawback is that it is messy.

Grease on the threads is a good place to start. Using a dedicated thread anti-sieze compound (available at any decent auto parts or hardware supply store) may or may not work better, depending on the parts involved and the conditions in which you ride. Avoid using cadmium-plated or zinc-plated screws in aluminum; nickel plating or black oxide or bare steel is a better choice there. -- Typoes are a feature, not a bug.

Perhaps not directly to your question about fasteners, but as rust has been an issue with your cro-mo frame you might want to spray inside the frame tubes with a rust inhibitor like Rust Check (similar to Wiegle product). Cheap way to extend the life of your frame.

For your stem, routinely remove it, clean, and regrease. Other bolts might benefit from annual removal, cleaning, and relubing. It sounds like these parts have been in the bike for many years. Check you seatpin too.

Yes and yes.
Grease all fasteners. Grease the seat post. Oil the spoke nipples. Use a good penetrating lubricant (not wd40) on frozen bolts, then wait 24 hours before applying heavy torque.
When buying a tub of grease look for water resistant marine grease, but any tub works fine.
