Yep, the Jaycar stuff deposits a visible white film when it has dried.
What I'd actually use on a Greenfield shaft, of what's on hand here, would be 'Optimoly Paste TA' spray, which is NLA now AFAIK. But that stuff was about $80 a can, when it was available [pre BP's takeover of Optimol]!
Cheers, Gadge
