Some Chain advice please...

I just GT85 regularly if winter riding through crap and leaving bike outside and I douse the whole drivetrain before leaving the clunkatron under it's cover for extended periods outside.

It's good enough for tank tracks

Its a bit ironic for me to say so, but Isnt GT85 like WD40? A sort of thin spray grease ? - thats "de-greases" chains?

Oh and in reply to everyone else,

Im not making any complaints about the kmc z chain, Ive ran one on my bmx for perhaps 8 years solid, and its been perfect.

But I didnt ride my bmx everday on rainy winter streets.

They gritted very frequently where I am this winter, and I just dont want the faff of having to clean & oil my chain EVERY time I ride it.

I think leaving it in an outdoor bike hut has nothing to do with it either, as theres other bikes in there plus Ive seen other peoples bikes left fully exposed all year round outdoors which look fine.

• My main query which I was seeking advice for was if any of those rust-proof chains I posted links of above^^ are long enough to wrap around 52-20 or 52-19 gearing.
  
  

I have a wheel with two cogs, one for 3/32 and one for 1/8
