So this is actually pretty good resin. I’m an artist and I use resin for casting in molds-usually pretty shallow. I usually use Amazing Casting Resin in white. It’s a quick curing resin that turns white when it cures. But that has gotten really hard to find. So I have this a whirl, and it was fine.A lot of people are saying that this is white; that’s not true. It only turns white if you DON’T MIX IT COMPLETELY! Once you mix the two parts together you MUST stir it; I would say for at least 30 seconds. Keep in mind the mixing speeds up the chemical reaction and will reduce your working time. But if you mix in small amounts you won’t have any problem.You can de-mold in about 15 minutes and they will still be a bit flexible and come out easily. After about 30-40 minutes they will be rigid but still come out easily.They paint up beautifully, and adhered to my furniture with e6000 glue. I made 450 molds between 1-6”Hope this helps.

I'm extremely impressed!!! I took the advice of another buyer that said to mix your pigment in the clear and then mix the yellow colored hardener and it worked great!! Only one problem, the seller has created a monster!! Now I'm going to be making things I don't need just because it cures so fast and good! LOL!!

This stuff definetly cures stupid fast. and you dont want to mix for too long or it will cure on you. It gets extremely hot, so wait before taking out of the mold. ideal when its cold or when the weather isnt predictable. I hate its so expensive for only 32oz. But this is seriously good stuff, you dont have to wait forever and quickly make casts

Cool stuff!! The resin sets pretty fast so work fast... get your color mixed on the clear side and dump in the yellowish side, mix throughly scraping the sides for about 15 secs and pour. I love how quickly you can make things. With clear resins you have to wait around 24 hrs but not with this stuff. I wouldn’t stir longer than 30 secs.

Once it cured it was a little more opaque than I was hoping for, but all in all it's a good product. And hard to beat for the price. One thing I would say though, not that the product isn't clear about it, but it's not kidding when it says that the working time of the mixed epoxy is only a couple of minutes. Point is, be ready to use it right away once you mix it.
