Thanks Gavin-this is interesting. The only product on the list that I use is Armillatox and I bought some earlier this year,it was classified as a path cleaner and no longer had the info leaflet on dilution rates for other purposes.
So-I wonder if I am breaking the law?-oh what the hel* I smoked a joint when I was 15 ;D(and long since stopped btw).
