Hi mate, I used this ,from memory, must have been 8 years ago?. Just followed the instructions. It seems to cover about 75% of the claimed area. 2 pack in a common bladder, once you burst the divider inside the bladder, get on with it , as it does "go off" pretty well to the minute they say it does.
Dries ultra hard, seemingly impossible to chip it by dropping stuff. Makes shed a lot lighter inside ( I used the light grey product). Shiney , but not slippery.
I DIDN'T add the supplied ' flakes' to it, as I reckon it would make it very hard to find dropped little nuts and bolts.
8 years on, I can't fault it.
