Shellac, varnish, parrafin wax for wood feedline spacers?

One suggestion I have is to look at cheap plastic coathangers. These are
about 1/4 inch in diameter and are not vinyl coated wire hangers. Several
insulators can be cut from a single coathanger. Since you can often buy
these hangers for around $1.00 for ten, a few dollars could provide a good
number of insulators. If you don't like the color, spray paint them with
Krylon or another acrylic paint. White will provide the best ultraviolet
resistance. I would limit my wire size to 16 Gauge or smaller as this
plastic is quite brittle.
Another suggestion: "They" make fiberglass driveway-marker rods which
seem to come in either 4' or 6' lengths. The ones I've used are 3/8" in
diameter and usually are painted International Orange and have a
reflective strip at the top. (Maybe more readily available in hardware
stores for "country folks" who need to come home down a gravel road in
the dark, with 2' of freshly fallen snow...)
I've not used these for feedline spacers, but they seem to be another
choice for that application. I've used them for VHF antenna
construction -- for both fixed and portable antennas.
