Dow Corning 781 Acetoxy Silicone Sealant Clear 310ml
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 :)

Slap it in your gun, aim it true and squeeze it hard for some serious H20 repelling magic.

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.
