Cheers Roy , I've got scotchbrite pads etc , I was hoping it would just miraculously lift off I'm putting it off cos it'c a tad chilly in there and not really the place to be crawling around on my hands and knees . I think sitting here in the warm in front of the laptop doing bugger all is a much better use of my time .
