Most people I know buy their ether in 2.5 Litre "Winchester" dark brown (UV resistant) chemical bottles with proper chemical Industry standard plastic sealing caps. They store their fuel in them as well, but tend to only mix what they need on the day. That way the fuel is always fresh.

Fuel stored in metal tins seems to cause rust blooms after a while.

I find that over a period of months glow fuel damages the plastic fuel containers as well. Someone said that it leaches out the plasticisers or something.
