Dow Corning 781 Acetoxy Silicone Sealant Clear 310ml is rated 4.5 out of 5 by 17.
Rated 5 out of 5 by from Totally recommend I believe this is the best silicone on the market. I have used many different types over the years and this is best for a long lasting professional level product. The only negative is the tip doesn't come with a cap, so once you have finished, any silicon in the screw in applicator can dry out and requires a bit of clearer out with a screw driver to remove. No biggie though and worth it for the professional looking finish you get with the product.

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 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.
