Review: Seems To Work Well On Silicone Rubber And Leather - I have some leather welding gloves that don't allow me to hold hot items for very long. I wanted to be able to glue pads of silicone rubber on the finger tips for better heat protection and improved grip. I have struggled finding an adhesive that bonds silicone rubber very well. Once dried the rubber just peels right off until I tried this product. The pads I glued to the gloves with this product adhered perfectly. I have to really pry and pull to get any separation. Even then the rubber tears right as it gets to the point of trying to separate. My next move was to buy the $30 Sil-Poxy. There is some debate whether that will adhere well to leather. I guess I will never know because for 1/3 the price this seems to do the trick where the other 5 or 6 attempts with various other adhesives failed. I will update if any issues with adhesion develop during use.
Review: Perfect for aquarium rebuilding - This is the same product that many of the aquarium builders use. This is an adhesive, which has a much higher tinsel strength and adhesion strength than the average sealant you get at the pet store. The working time is around 12 minutes. You need to plan out your assembly and go through a dry run or two before actually attempting to put it together for real. The tube was well within date, it was only a couple months old when i got it. If you are doing a tank bigger than 5 gallons, consider the calking tube. This is not the easiest to use to lay down a long even thin bead and keep it smooth and straight. It takes a decent amount of pressure with a thinner bead, you may run into hand fatigue by the time you are finishing up.

I used this with glass shower door clamps. I tried others which resulted in a slow slip. This is the only thing that worked for me.
