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?

You can't apply it below a certain temperature. It won't come out of
the can. I think the propellant liquifies. (Refrigerant gas)

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.
