Dow Corning 781 Acetoxy Silicone Sealant Clear 310ml is rated 4.5 out of 5 by 15.
Rated 5 out of 5 by from Perfect for my needs I chose this sealant for its inert properties as its used to seal a 6ft vivarium housing a boa constrictor. Much cheaper than some other online aquarium sealant most people use and does the job well from a well known manufacturer.

Rated 5 out of 5 by from You won't find better I spent a lot of time researching all the forums before I purchased a sealant for my bathroom, as the previous one lastest about a year before yellowing. I replaced it all with the white variant 2 years ago and it still looks like new. I now use the White 785 and Clear 781 versions for every application and wouldn't use anything else.... It's superb! I can only rate it 4 stars for reliability as I've only been using it for 2 years but I have no doubt that it'll continue to perform perfectly and look as good as new :)

Rated 5 out of 5 by from Sili sealer Slap it in your gun, aim it true and squeeze it hard for some serious H20 repelling magic.

Rated 5 out of 5 by from Easily the best Silicon 36 years of Tade and DIY and this is easily the best sealant you can buy. It is easier to use than most and will outperform and outlast any of the others. Purchase the correct grade for your specific application and you will end up with a long lasting professional job.

Rated 5 out of 5 by from Best sealant on the market ! This is the first time I have used the Dow Corning brand sealant - It is a far superior sealant to all the other sealant brands - it is so smooth when you apply it and it leaves a perfect finish. I have used it to seal around the sink. I would highly recommend this sealant and it is also very reasonable in price from Screwfix.

Rated 5 out of 5 by from Great product! As a DIYer I don't really mind this being a bit more expensive than others; the only thing I want is a quality product that's easy to work with. I'd rather pay £2 more and get a good result. I don't have that much experience with different brands of silicone, but this is great stuff in my opinion.
