Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
This was supposed to be a box containing both Part A & Part B of Vytaflex 30 rubber. I received a box containing (2) Vytaflex 40 jars - both part B. They are different shaped jars, and the wider one had dust all over the top. I didn't notice the discrepancy until i had mixed them and waited for them to harden, and they never did. Shocker. Disappointing waste of time. Returning for credit.
I create props and other casted items. This is an easy 1:1 peach colored urethane that takes a full day/night to cure, but is well worth the wait. More durable to repeated demoldings compared to silicone in my case (my casting material is abrasive/sand-based and tears up silicone). I find it's best to vacuum degas the mix to preserve the mold details better since I use pressure casting techniques.
I'm in Texas and know I should be purchasing from my regional distributor that's about 350 miles away, but shipping from Smooth-On directly in PA (via Amazon) cuts my shipping cost in half. Same carrier and everything. Strange. Anyway, shipped well packed, quickly, and with no damage.
A little slow slash humidity sensitive to cure, hard to tell if thoroughly mixed, if you think it's mixed mix 5x longer (clear and color resin can be hard to judge when mixed)or it could be slow and or patchy. You have the wait time...so much wait time. Sturdy however would buy again.
This stuff was super fun and dead easy to use (it doesn't get much simpler than a 1:1 mixing ratio). I didn't use a mold release agent, but my mold peeled out just fine. Your mileage may vary. I would definitely buy this again.
