The mold was easy to use and you have plenty of time to cast it. I used the mold to make a couple of rubber gaskets used on a through deck cable gland and the parts I casted were absolutely like the original. I highly recommend their products.

A very good product that’s durable and easy to use, but now messier
A very good product that’s durable and easy to use. It’s comparable to similar silicone products, like Smooth-On Mold Max 25.
My only complaint was that they changed the packaging from a clean, easier-to-use plastic bottle with an actual pour spout, to the much messier drum that results in your entire workspace being dribbled with sticky silicone. It’s like they are trying to emulate the Smooth-On products, which also use the drums. What-a mistake.

The Silicone and the Urethane resin did exactly what I wanted.
