    More bang for your buck but with a few minor cons

    Posted by Suzanne E Brown on Sep 24th 2021

    First off I like how flex it 90 has way more resin at the same price as it's competitors but gives you way more resin than those other brands. The resin feels similar to PVC durable rubbery plastic which I wanted, like those store bought action figures. So if you are making a action figure, this is pretty good for that. There are a few cons that I feel would improve the product exponentially which is why I only gave it four stars this time: Cure time is too fast: I barely have enough time to pressurize it or check to make sure it's seeping into the nooks and crannies of my mold. I wish the cure time was a tiny bit longer. Like 7-10 minutes The resin isn't water white clear/transparent: It's very hard to color match the resin. The amber color darkens my pigment powders and I can't do bright colorful casts. Or do transparent candy color casting with it. Other than that, a great product and you get a lot of resin to use for a decent price. My only cons are cure time to fast to pressurize and pigmenting it a certain color is a challenge.
