I haven't checked to see what if anything Packard recommended but DRY powdered graphite would at least be a safe choice, might help & can't hurt. It's an excellent lubricant, often recommended for key locks, fishing reels, etc. I wonder though how long it will stay in place with the pressure of the exhaust gases working to force it out.
