How did it happen ? Were you rough with it or is it just so `light` that it tears easily? I suppose if you have no proper system tape, Duct tape might help.......as far as I remember too, I was told before, that SMALL holes and tears in Poly can be stopped from spreading by dabbing on nail varnish [you might get some `odd`looks if you go into a shop to buy it though .....``Which colour would Sir like``?..``Oh, I`m not fussy really `` -- LOL ! ] I can`t swear to that as I`ve never tried it and it probably wouldn`t be any use if the tear was right to the edge of the perimeter ( you said it isn`t ).... the newer `skin`systems might not cope too well with it as they are quite thin. Let us know how it goes anyway...be interesting to know ..cheers for now, Paul.
