I make most of mine from MDF, sometimes from ply, and I have trouble
with damp in my workshop. All of mine get a coat of wax - it's an
ugly colour that Axminster once shipped to me by mistake and I've no
other use for it anyway.
I also write on them what they are, and what size (if relevant) to
prepare the stock to before using them. Saves a lot of trouble in the

It seems that I always mix up more shellac that I can use project that I
mixed it for. The extra usually gets applied to jigs and such. It is a
great way to us extra shellac and it protects the jigs.
Depends on my mood. I spray painted a couple of my router fences, poly'd my
router box making jig, but my crosscut sleds usually only get paste wax on
the bottom and the runners. However, I made a little jig for cutting narrow
pieces on the tablesaw that ended up getting French polished.
Either a couple of coats of Trewax or same of Dalys Sea Fin Teak Oil.
Anybody recall my 'the ADZE' stories? Well the fellow known as 'Little
Hat Shapiro' was a true life person and his well equipped commercial
woodworking operation called the 'Sonoma County Woodworks', had the
walls hung with his jigs. A horizontal strip of 2X stock bored to take
dowels and the jigs hung on the dowels. Very impressive to prospective
clients to be sure and they were damn good. Well designed and made.
Some times I thought he liked making jigs to do functions more than
doing the actual work!

Best argument for finishing a jig is to put a water vapor barrier on it
to minimize dimensional changes from humidity changes. Best finishes
for that purpose are shellac or solvent based polyurethane. Non
silicone containing wax on top of the finished parts of the jig that
need to slide is also a good idea.
Yes, (both jigs and templates) depending on what I happen to be using the
next time. I'm doing some finishing. If for no other reason than to keep
them cleaner. I also mark them with their intended use and any critical
