Rated 4 out of 5 by from Good roof sealant Good stuff for sealing those very annoying corners on roof windows where the manufactures flashing is not up to the job. Also good for sealing gutter joints when using different manufactures products that don't quite fit as they should. A bit pricy for what it is though.

Rated 5 out of 5 by from silicon you always get value for money from screwfix. This silicon is excellent and not watery like some you buy. Highly recommended

Rated 5 out of 5 by from Dow Corning 791 After trying to find a silicone that would stick to perspex (clear polystyrene sheet). This is the only one that worked for me. Other neutral low modulus silicones may work to. I would stay away from silicones that contain acetoxy when trying to stick to oily plastics. Only give 4star rating for reliability because it hasnt been on for long so I dont no how long it will last.
