Is PU expanding foam resistant to water (and cold)?
What should I use to lubricate zips on an awning?
Thanks

Water, generally yes. Cold certainly. Breaks down under UV exposure though, so you need to take care with it outside.
Chap-stick / lip balm is one commonly used on plastic zips. Graphite can work well on metal ones.

Wax from a candle rubbed along it? Or a silicone lubricant?
yes,. and up to a point.
Silicone grease..you can buy tubes, or spray cans.
I've got a spray can if silicone dry lubricant that I use on the padlocks for our sheds etc.; I expect it'd work very well on zips, too.
