Just received a bottle of this lube and applied 2 coats last night to a fully degreased and dry chain as instucted. Application was easy, went on nicely etc. I checked the chain this morning and can’t see any sign of it on there, chain feels slightly greasy to touch but less so than normal dry lube is this normal?

Also, how often do you need to reapply the lube for best performance?

It does dries pretty clear, but will get a bit mucky once ridden. But it’s easy enough to clean it down and re-apply as it does not attrack too much grit.
It does come off pretty easy in the wet, so re-apply as soon as you finish a ride.
But in the dry it can last a fair while, I only re-applied to my commuter after a month of small daily rides.
I use it on my road bike as well, with no problems.
The best thing is to let it dry on the chain as you have done, it just spins off if you put it on wet and ride straight away.

Ok cheers, will give it a go and see how it runs

you just need to remember to reapply it after a ride. If you apply it just before, like you would oil, you are wasting your time
