Dow Corning 791 Weatherproofing Silicone Sealant Brown 310ml 4.7 5 6 6
Good Performing & Flexible Have used the 791before & rate it highly. Easy to use, as all silicone tubes are these days, but without any odour or fumes. Brown is a good colour for 'losing' around joint edges, whereas black or white stand out. Has stood the test of time so far in the face of wind and rain, and remains very flexible which is important on outdoor uses. Would like to see it a pound a tube cheaper, but acceptable now. Recommended. 10 Dec 2014
Just what I needed Easy to apply and clean off. Torrential rain 1 day after application and no sign of any leakage. Marvellous stuff. 25 Aug 2014
Great product Being a DIY'er, one of the jobs I always hate is using silicone, as it usually ends up everywhere. I was recommended this product by someone in the trade and to be honest, all my "fears" of using silicone have gone. It's easy to apply and cures quickly and even with my DIY skills it gives a "professional" (apologies to all the pros out there) finish. Quite a bit more expensive than other products, but well worth it in my opinion. 19 Sep 2012
Works well Easy to apply, sticks well, easy to smooth out. Only time (a few years) will tell on reliability but I am happy with it so far. 20 Jul 2012
