AE6KS

the roll here is bright white.

usually Weldwood red on nylon ....eg tent repair https://goo.gl/3BB7m6

for wire ID markers ? the wiring is in the van so not toxic is required. I sleep in van then work with birds in the field at sundown/sunup checking behavior patterns with mobile MiFi USGS Earthquakes real time mapping.

Loctite fabric glue might be relatively non toxic in the very small quantities needed. The stuff at Walmart. Not construction or outback levels... Weldwood red does not come apart, Loctite does separate under pressure...but for a wire marker ?

tried Loctite as a filler around primary wiring...some Pico...running thru nylon tube fluid/air wall fittings finding the Locktite held wiring inplace and sealed out water ...this on pelican boxes sealed with 3M Marine soybean oil. Should work on uncoated flag cloth.

Flags are expensive.

on the yak or abs canoe....for long exposure trips out west where the sun shines...the covering is held on with shock cording n strapping...commercially developed models available.

now find ink .....
