I'm sure I used GT85 for years and had roughly the same drivetrain life I get now. Doesn't last as well a proper lube though.
I'm reading this thread with interest as I've just run out of my favourite Joe's Wet Lube and it has been dicontinued.
Not impressed by RnR when I tried it, Weldtite wet lube was cheap but seems a bit sticky (a la Finish Line wet). Don't really get on with dry lubes.
Anyone recommend a nice light wet lube?
