Hi Ember
Thanks for the info, unfortunatly Prepsol seems to be hard to find in UK from what I can see on Google. Going to try a local paint supplier and see what the do as I also want to get some tack-rags. If not Halfords (UK national Autopart warehouse) do a preparation spray that seems similar and some pre treated cloths. I'm a little worried as a lot of my track is secondhand and I don't know how much use it has had and how much rubber I've got to remove.
