Rated 5 out of 5 by Great sealant Used this on my garage door-to-brickwork join, resulting in a very neat finish. The brown is slightly dark and blends in well with the brickwork. Will use again if I need to - excellent! 5 Nov 2015
Rated 5 out of 5 by DowCorning 791 weatherproofing It is a very nice shade of brown and a texture to match. Only Dow Corning can produce such a high quality product. A little dearer than the others but well worth the money. My wife was complaining of wind whistling through the back doors, due to a large gap. One tube of 791 and peace, quite and tranquillity to our wind free house. I would not hesitate to use it again. 2 Nov 2015
Rated 5 out of 5 by brown sealant applies easily, gives good adhesion and leaves a fine finish 23 Aug 2015
Rated 5 out of 5 by Sealed I purchased this on the strength of other reviews. I was not disappointed. It is easy to use, sets quickly and odour free. It easily filled the areas that I needed to between wooden door frame & masonry. Not the cheapest product but it works well. 1 Jul 2015
