Bob, in the UK, 'Future' is called Johnsons Pledge Klear. (was just Johnsons Klear), and is milky until used, when it dries clear. It used to be ..er.. clear, until the name changed.An alternative of course is normal gloss clear enamel varnish, such as Humbrol.
I use both, normally using the 'Klear' (Future) mixed with Tamiya Flat Base to produce, matt, semi-matt or semi-gloss clear coats.
