Gomog .... I'm never without a can in my workshop (OK, several cans 🙂) ..... as I said, a really useful diagnostic tool .... with a public forum you never know know how much 'bushcraft' other members have ... the OP may be well versed in ether sprays and I'm teaching my granny to suck eggs... but also might not be and spraying it onto a source of ignition would be a surprising learning experience out of the blue! 😄
