Dow Corning 791 Weatherproofing Silicone Sealant Brown 310ml is rated 4.6 out of 5 by 21.
Rated 1 out of 5 by from Beware!! - Not BROWN Disappointed - very - with this D&C product. Came with a brown snout. It even looked brown. But it dried like a Rich Tea biscuit. Spoilt the entire effect I was trying to achieve and I had to start over ... with Unibond. At least Unibond exterior sealant is actually BROWN out of the tube and when it dries. Moreover, this D&C product DOES NOT colour with either creoseal or woodstain - Unibond most definitely does. I would never use this product again. D&C internal sealant is fine, but, for me, their external stuff leaves MUCH to be desired.

Rated 5 out of 5 by from Reliable Product Costs a little more than other outdoor sealants but it's worth every penny for peace of mind. This is totally weatherproof, it's very smooth and gives a great finish, it'll give you peace of mind for years to come, highly recommended.

Rated 5 out of 5 by from Great Sealant Used on old French doors to seal around the panes. Worked well and is hardly noticeable due to the colour. Easy to use, and non/little odour which isn't always the case

Rated 5 out of 5 by from Excellent frame sealant Have used a more expensive product for sealing around external window frames a few times and having now used this product I will be using again, I would actually say it it easier to use and of a better consistency than the more expensive brand, highly recommend this product!!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.
