Let me start by saying I've used a LOT of resin pigments, and this one is... complicated. The 'Easy Flow White' definitely lives up to its name when it's fresh - it blends into epoxy like a dream for creating those realistic ocean wave effects I love making for my coastal-themed decor.
When the bottle is new, the pigment concentration is impressive. Just a few drops gave me that perfect milky white for wave crests. The squeeze bottle design (when clean) offers great control - crucial when you're trying to nail that translucent water effect.
BUT - and this is a big but - storage is everything with this product. Like several reviewers mentioned, it dries out faster than my patience when I'm mid-project. I've learned to transfer leftovers into airtight containers immediately. The packaging quality is hit-or-miss too; my last bottle arrived looking like it survived a warzone.
Pro tip: It does take more pigment than expected to achieve true opacity for white waves (contrary to the 'little goes a long way' claim). I go through bottles faster than anticipated, so buy extra if you're doing large projects.
Despite the flaws, when this product works, it WORKS. Nothing else in my studio creates such natural-looking water movement in resin. Just be prepared for some quality control roulette and have backup sealing methods ready.
