That sounds like a pretty nifty trick Big Rob, will try it on mine when I get back to it.

I went for a Clark rubber product for this replacement also, but havent fitted it yet, on the weekend I went to do it my local Clarkes didnt have a size in stock that fitted well enough, I got some that was slightly too thin and some that was slightly too thick, but hairspray eh? Nice tip - that might get the thicker stuff to slide in ok!
