Review on 🔧 Smooth-On Smooth-Cast 325 ColorMatch Liquid Plastic Compound – Ultimate Crafting Material for Adults 18+ by Barbara Simmons

Like most Smooth-On products, this material works as it should. Mix equal parts A and B by volume, pour into a mold, very easy. The only thing I didn't really like was how insanely short the shelf life is. Yes it's listed as 2 minutes so I was warned but it's still not that much time for anything and it has made it very difficult to get good results as you barely have time to mix the resin and close pour, not to mention doing something like vacuuming to get rid of air bubbles, and there are a lot of air bubbles. The best workflow I've found for this was to degas parts A and B separately, then mix and pour, then move the mold to the pressure chamber (quickly!). Even then I kept finding air bubbles in the casting, which was a bit annoying when using clear resin. In the end I can't fault the product too much as it actually preforms as advertised. However, if you just NEED a super fast curing resin, something like Smooth-Cast 326 or 327 is better for most applications, which have a longer pot life, making the workflow much less hectic. The fact that every Smooth-On product looks the same can be blamed on the product. I accidentally wrote my review of their Oomoo silicone on this product, oops.
