Kettle water measurement - how to

[fraser_john]

I etched permenant 5L increments on the inside of my 50L HLT
Its really easy and you can use vinigar and salt to make an electro-etchant. All you need is a 9v battery some wire and a cotten tip.
Just google etching stainless steel and you will find it.
Looks awesome, I only put lines in mine but have seen some really fancy marking guys do on their pots.
Not sure if it works on alluminium though.
