    Customer Service and Timely Shipping

    Giving 5 Stars only because I'm overall really happy with the product and customer service but man is been hit or miss over the years. Often times I've called in an order, paid, then somewhere someone drops the ball and it sits for a week. being in always trying to have fresh resin, this timing can be ruined by a late delivery. Thankfully their customer service team has jumped through some hoops to get my orders to me quickly once complained. For those guys... They earned your 5 star rating. Ask For Cody if you need help and he deserves a bump for putting up with me. ?❤️‍??

    I'm using this type of resin for the first time. I have worked a lot with polyester resin in the past. I like the fact that polyurethane resin is almost odorless and it seems to be very resistant. For some of the figurines that I make, I have a problem with the weight; it is too light. I still have to try to use some calcium carbonate as a filler, as I did with polyester. I find this resin very "unforgiving". I think that I have mixed it very well every time. However, I went through several instances when it did not harden well. I definitely have to try the one that allows more working time. For some of my models, it will work really well. Same when I have to make several copies to make more molds; it is easy to do some retouching. It doesn't work well with latex molds, for some models I'll have to switch to RTV. Finally, I would like to try some good technical support. The time when I called, the person who took the call tried to be helpful but was not a specialist on this product, and I could not get what I needed. I have to keep doing some more testing and see if I can use it. It would require a huge change for me to go back to polyester, because of the odors. My shop and my location are not compatible with polyester. Whether I make it work with this resin, or else, I'll have to get a suitable shop where I would not have a problem with fumes and odors. I'll keep trying.

    I've been using this resin for prop-making for the past couple years and it's an outstanding product. I've not had any break during shipping, or reports of breaks/cracks from customers using my props. You can spend money on a name, or you can purchase an outstanding product like this and you'll be far happier.

    A good and affordable resin that serves as a substitute for Smooth-On 300. It has a slightly shorter work time, and can be a little bit brittle for thin items, like fingers, but overall a decent product.

    Fabrii-Cast 50, is a winner of the polyurethane casting resin for me. It works as expected by curing finishing as needed to expected results. Thank you for this excellent product.

    It worked out great. I'm a taxidermist in south Louisiana and use this product to make artificial alligator tongues for a head mount.

    Worked our like I hoped it would.

    Like the resins very much

    Wish the slow and extra slow urethane resins were available in the same ultra low viscosity and possibly in bright white as well
