Have Sterling Eccles Topaz. the sliding roof blind is showing some daylight through cracks in the material . They are only in lines about 5cm long by the hand pull. I took a look to see if I can take off the "handle" , shorten the blind and refit but could not see how to remove the blind, unlike the window blind ones. My second thought is to paint silver something over the cracks but that might seep through to underside of the material. The blind is made with two parts , one is silver coated other white/cream then "stuck " together. Any further ideas would be appreciated .
