This is trivial (and may be common practice for all I know), but it works so well it seems worth sharing. The ongoing plane tuning intensive was leading to the usual struggle to get wax protection on to especially stuff like threads and unpainted adjusters using a cloth - with the spray camelia oil used for awkward bits going all over the place.
A flash of inspiration led to a 1/2in cheap stiff bristle glue brush being pressed into service. Like this one: http://www.cottambrush.com/collectio...-paste-brush12
Putting wax on with a brush turned out to work really well - at least with Renaissance which is quite oily. (like very fine wax particles suspended in an almost liquid) You might need to test a (harder?) car type paste wax for brush ability, or it they may work just fine. No problem at all with the Renaissance to brush on a coat that covers absolutely everything - into the threads in holes and on studs, crevices, slots in blades, knurls on knobs, grooves etc. - and reliably over every square inch of the larger surfaces too. Let it dry for a bit, then polish the surfaces likely to be handled with a cloth…
The key is that it offers the possibilty with just a little care of greatly improving the corrosion protection by getting more or less 100% coverage of all surfaces on the tool (strip it right down to its component parts first), and does a nice job of lubricating threads and sliding surfaces too. No reason then not to top up the protection in use via the usual quick flash over with a cloth to re-coat the sole and the areas that get handling - with the option to top up the brush job when the tool is next taken apart...
