there was some containers in b&q plumbing section that were sealed with a threaded lid could be worth a look matt .
cheers, i will have a look
I saw some barrels at my local garage (too far from you) but you might try yours?
They looked like the 25 litre jerry cans/containers (square) but taller.
Looked like they had antifreeze or something in.

i have 15 X 25 L barrels, i just need something a touch bigger, the 1's you saw are used for the car wash
