Review on 🔥 Permatex 81878 Ultra Copper RTV Silicone Gasket Maker - 3 oz. Tube | Maximum Temperature Resistant by David Dortch

I used this to make "silicone boots" for my Monoprice Maker Ultimate 3D printer and it seems to work pretty darn well for that , as opposed to from mixing my own weird silicone grout. Using a 1bigpig thing that was printed with black polylactide, I coated the inside of this thing with Costco dish soap and then squeezed just enough to fill maybe 2/5 to 1/2 of a container and then squeezed. A day later I received a usable silicone case for my printer. I definitely had enough to do, at least 6 before deciding to quit and I could have done 2/3 of the tube. Your hands or other surfaces it comes in contact with will stain the copper a bit, so I'll be careful with that. It washes your hands but requires some work. but it actually seems to handle my 260°C print temperatures without issue, so I'm happy with that.
