I think that's what i'll do, although i'm undecided whether to go for 2x2.5L tins along with the sprayer. I guess i'm talking £40 with one tin, although i'd like to start and finish it on Saturday. It would be a killer if I ran out when I was nearly finished and had to take a trip out to Halfords on SundayIt should be enough to start with, at least if you do run out its easy to get. DO MAKE SURE YOU READ THE TIN otherwise you may pick up the black instead of the clear. And yes that's the kit.

The kit with the proper canister sounds like the best way to go as I won't need to brush it on and i'll get the sills too.
