In general discussion, when we talk about thinners, then the thinners used
in that particular industry is the one being discussed.

So it seems there are differences in terminology, between the US and
Australia (funny that) that can lead to some confusion.

Zactly. In the US, paint thinner is mineral spirits, no matter where you
get it. In an automotive type supplier, if you want to reduce the
viscosity, you ask for reducer, then specify the slow medium or fast
reducer. Ask for paint thinner at one of those places, and you will still
get mineral spirits, but they probably will not have it.

I did not realize that this was yet another example of terminology
differences.
