I used this product to fill in some custom square tube steel bump stops on my truck. The 1:1 mixing ratio made it super simple, and the black dye looked great. It started hardening just a bit faster than I was expecting, but probably because I stirred too long, poured too slow to avoid air bubbles; like the title says this was my first time ever using this so no doubt it was my fault. Regardless of it curing toward then end I got it all done just in time with no issues. I can’t wait to find more uses for this stuff!
Material looks and feels like the rubber material used for SCUBA high pressure vintage 1st stage regulators. We'll see. Looks really good.
Great product, perfect hardness for my homemade gaskets
Where can I buy this chemical in Nigeria, please any idea let me know.

I've used this for several projects for prototyping parts in the mining industry, the higher strength is required and it's important to plan for the short pot life. Set a time, mix for 1 minute or until it starts to get warm and then start pouring your parts. Great product but make sure you are aware of the pot life, no time to de-gas it, just mix and go. bubbles are a minimum anyways.
