I have only ever purchased XIM once about 7(?) years ago. I think that was when the UK distributers of Owatrol were first pushed out of the door by the makers of Owatrol.
At the time it was a thin blue liquid sold in a bottle like this
I see that the bottles have now changed. Is it more like Floetrol in consistency now?
Years ago I did purchase some Propylene Glycol, after being told that it is the main constituent of Floetrol. I must dig the bottle out and see if it works as well as an extender. It is way cheaper than either branded product.
