Review on Crafter's Companion A20501 Alumilite High Strength 3 Liquid Mold Making Rubber, 1lb, Pink by Tara Williams

Just make a note of the mix ratios, I did it by volume which took a long time with the spoon provided. Next time I'll use a kitchen scale and mix by weight. I used this kit to make an intake port for a Honda cylinder head. I also used silicone spray lube as mold lube before casting. I let it dry for 2 or 3 days before attempting to remove it, this material is STRONG, I separated the rubber from the metal as best I could and then just grabbed a large well and pulled until the shape came out. . It took some effort, but it didn't even leave a mark on the mold. Very happy with the results
