Ahh I stand corrected, It's from when I used to fix punctures as a kid on tractors (20 years ago) we use Vulcanising Cement Fluid, Thats doing a different thing tho, just looked it up and realised were I got my wires crossed but always did find science boring as hell

last post corrected

Now off to join Col at the top of his polly butler pit box,lost the will and going to throw myself off! As I now Can confirm I was crap at science but still no clearer.Is this just a misinterpreted conversation at a race meeting, or a coming rule change effecting what we have and what we may use in the future
