Does the PTFE dispel water, freezing is sometimes a problem in Winter ?
I guess it does, as plumbers use PTFE tape and paste to seal threads etc on fittings.
I have the WD40 PTFE spray and the white lithium grease spray.
I just favoured the light weight white lithium grease.
A lot of manufactures use it on contact points like door locks / check straps / window regulator mechanism’s etc.
But not MG it appears ?.
My car is parked outside on the drive, last winter when it was REALLY cold, the drivers door handle would not return at first when I opened the door.
It needed a bit of help to return it to the closed position.
My previous VAG car never did this.
It will be interesting to see if it does the same this year, now I have applied the lithium spray grease !.
A family member also has a ZS EV and his rear drivers door handle was sticking when it was really cold.
As soon as the morning frost had lifted, the handle worked fine every time.
He used the standard WD40 spray, which if fantastic stuff to free off the problem, but you need something else to back it up, or after time it will dry out.
That’s where the lithium spray comes in.
Time will tell I guess !.
