I have been looking at ordering some extinguishers for the company vehicle fleet and found 2L AFFF ones for about £35 or so just using Google. 1KG dry powder I found some from just £8! Gonna add a couple on for private use I think...
Why not get them for £23 from Peter Lloyd Rallying - very reliable company that have been around for many years!!!
I was away in Spain at the time!!! Besides which the powder gets everywhere. Most of the older powders are ammonium or sodium bicarbonate - good old baking powder but the ABC type is Ammonium Phosphate. This corrodes aluminium and galv in record time - doesn't do steel much good either - literally straight away with the heat present.
