    Great Customer Service and Product

    I have been buying my resin for about 2 years from this company! I love that this resin hardens fast and is bright white..exactly what I need for my little business! Their customer service is also outstanding, I once ran into a problem with a bad batch of resin and they went above and beyond to help out and resolve the issue! I can highly recommend this company!

    Fabri-Cast 50 Bright White for Models

    I've been buying this stuff for a little over a year now. I prefer the Fabri-Cast 50 over the Model Pro because I can sand it a bit better than Model Pro. I almost always use microballoons in my pours as filler and I'm glad I do. It helps combat small air bubbles that can form. I've noticed that Fabri-Cast and Model Pro both result in a trapped air even with spew holes. Maybe I need to add more breathers but the microballoons help combat that issue. This stuff also can be demolded in less than the recommended 10-15 minute timeframe which is nice if you're try to maximize your production. I'd average about 8 minutes from pour to demold, for best results I'd wait the full 15 minutes however.

    Fabri-cast 50

    I mass produce fishing lures at home. Fabri Cast 50 is most economical and easy to use product. Very fast cure time but forgiving if not mixed exactly to specs.

    Excellent resin for costumes!

    I've been using this resin for over a year now and have pulled several helmets. It's an outstanding product which in turn makes the pulled items equally outstanding. Listed pot life is pretty spot on depending on your ambient temp, and it holds pigment really well. I would put this resin up against any of the more expensive brands any day, and look forward to my using Fabri-Cast for a long time to come.

    fabricast 50

    This resin is so good!! the cure time is nice and fast and its pretty durable when its all done. interesting note it cuts through a bit softer than some other resins ive used so that’s definitely a plus for cutting off gates, mold lines, etc. not my favorite for dying though but thats okay because it generally accepts paint pretty well. all in all really great to use! i make bootleg toys with them so keep in mind this is all small stuff, i dont have much experience using it for anything bigger than a 3.75” figure.
