GT85 is akin to WD40 - it isn't heavy enough to be chain oil, and will flush out any "proper" chain lube from the rollers. DON'T USE IT ON YOUR CHAIN (unless you can reapply it OVER and OVER again).
It is good for derailleur pivot points etc though.
I reckon you should have three types of lubrication in the garage for your bike.
#1 - Chain Oil
Personally I have two - Weldtite chain oil, about £2 from my LBS and Finish Line Pro Road Ceramic (from Evans, £6.99). Use for lubricating the chain, I also use the weldtite stuff for lubricating shift cables. I've used this on spoke threads as well.
#2 - Grease
I use Bikehut teflon grease, although ordinary brown grease would do as well. A grease gun (mine was £7 from Halfords) makes the grease much easier to apply. Use this for greasing seatposts (so they don't seize) bolt threads, quill stems, etc etc.
#3 - Some sort of spray light oil/water displacer
I use GT85, which (apparently) leaves a PTFE coating behind on the lubricated parts. Use this for spoke threads, derailleur pivot points.
