I have used this product for years and the last few years I've always ordered it from Amazon as I know what I'm getting and it's obviously delivered straight to my door and it's never going to get returned.Bond It HA6 RTV Silicone is a different league to standard Silicone Sealers. It has a far superior bond, flexibility, and heat and cold resistance making equally good indoors or outdoors. Basically this will hold your greenhouse panels in just as well as it will bond your fish tank panels together and as long as you prepared your surfaces beforehand you'll have nothing to worry about.Now here's what I like best and I discovered this by accident really. About six years ago at least, I sealed all my showers, sinks, bath and toilets with this exact product. I already knew this stuff had a strong bond so I didn't bother screwing the toilets down to the tiled floors, I just bonded them down and filled the screw holes with it too as it looks so much better. The same with the sink pedestals too but that was because I couldn't be bothered with faffing around marking and drilling holes around the back and inside when I knew it was going to hold perfectly well anyway. So, 6 years on when we decided to move a toilet I challenged my builder friend to break the bond. There was no chance whatsoever as we knew we were going to break the toilet first, so out came the utility knife, and then the extending craft type knife as we still couldn't budge it. But, that's when the penny dropped, not because of the bond but why I resealed everything in the first place. It was because the guaranteed mould and mildew resistant Silicone Sealant we had used before was going black everywhere, everything looked so dirty and ugly, and after less than 2 years was it so deep in the Silicone that it all had to be removed which had lost its bond anyway and easily pulled out like rubber bands.We had totally forgot about mould and mildew basically because we don't have any anywhere, absolutely not even a single spot after 6 years and it's still going strong!I actually use this stuff for everything now from fixing the kids broken plastic toys, the builders bait boat, the father in laws classic car delaminating vinyl dashboard and gaskets, etc, etc. ### ⭐⭐⭐⭐⭐ Quality *by on Reviewed in the United Kingdom 22 November 2025* Top quality Silicone ### ⭐⭐⭐⭐⭐ Quality 5* *by on Reviewed in the United Kingdom 11 March 2025* RTV is the better version of silicone in my opion well worth the extra money. If it holds fish tank glass together, that's good enough for me.
