Deep the rabbit hole is....
Thanks for the feedback, dfb. Have bought the reload, the carpro elixir and a couple more towels. The reload will go in back of the cupboard in favour of using the detailer for now.
Im thinking that maybe the streaking im getting with jet may be an indicator of product overload on the paint surface.
After watching some vids, also realised my towel cleaning regime needs to include soaking.

This should be enough to keep me amused for a while. Thanks again,
