Well, Clonex is an Aussy product, so I imagine that he is patriotic.

well... I actually prefer traditional rooting powder- in rockwool, anyway. Powder forms a paste which stays put better in rockwool than gels through several waterings. Any rooting powder with ~8% butyric acid will do. I use the Rootex-P brand.
Soaking stems in plain Clonex gel for a while may or may not be helping. The stem might be picking some up, might not, hard to say. Any gel on the outside of the stem is sure to be rinsed off quickly in a DWC or aerocloner, so soaking for a while is probably the
only way to get any butyric acid in the stem for those applications.
Gel has the downside of being able to support pathogen growth between passes of cuttings. Once gel has had stems dipped in it, it should not be used for another pass of cuts. Portion out a small amt of gel into a small separate container or jug cap for dipping and keep the rest of the uncontaminated gel in its container in the fridge. Discard any excess which has been used for dipping or soaking.
