Review: Flexible neutral cure Silicon but not 100% - The unique thing that differentiates this from the red bottle 💯 "glass sealent" silicon from the same company Dow is that this is flexible. It's also a neutral cure Silicon and doesn't smell like vinegar while drying/curing. Pros: You'll get more time to "tool" and set this one as compared to the other 💯 silicon. 10 mins as compared to 5 which might be a great advantage for some beginners using silicon. Con: It is not 💯 silicon and if some people might not like it's flexible joints. If you stick glass with it the panes will move quiet a bit that might scare some people but that's a feature of this silicon type not weakness. General info states this type is stronger than acetic cure silicon but official website of Dow states it's tensile strength weaker than 💯 glass sealent silicon from Dow which seems to be a favourite with aquarium DIYers. This is more of an all purpose silicon which also works on glass.
Review: Best for glass joint - Best for glass joint, i used this on my roof top glass joint
