So I have used probably 20+ different brands from cheap to way over priced. I was looking for a new brand that i could use only their products. Let me tell you, this has the most perfect viscosity of ANY resin i have tried. So my first trial, I was top coating tumblers. Here is what I found:1. My room temp 68.4 F2. Humidity: 53%3. Batch size: 30 ml4. Mixing review: started mix at 1015am. Gorgeous low viscosity, mixed 3 minutes with popcicle stick, since they produce more bubbles. Quick mixing and ribbon dissipation with scraping sides and bottom of the cup. I'm a nurse by trade and have the nose of a bloodhound and this has very little to no odor in my working environment.4. Degassing: bubbles released immediately in this small batch.5. Work time disclaimer: GET EVERYTHING READY BEFORE YOU MIX! Be prepared to start at once. This cures in 1 hour so working time is less than 10 minutes.6. Work material: glitter burnished stainless steel 20 oz tumbler.7. Application: resin glided over the glitter with ease. Application was like silk. Drizzled slowly on tumbler as it spun on turner and coated with gloved hand. Resin covered and self leveled quickly. Ran torch over quickly to pop any friction bubbles from rubbing product on. Left to spin dry.8. Resin was noticeably warm by minute 6 and started getting thicker at minute 10. But was still workable.9. Outcome: cure to fingertip touch at 45 minutes. And at 1 hour if you pressed your fingernail you would leave a slight indent. Full unrestricted and unprinted cure at 68.4 degress achieved at 1:30 minutes. I'm sure if my studio was over 70 it would have been much quicker. Overall, the 1 hr fast set from promise has luxurious low viscosity, easy degassing, mixed like butter and amazing cure time. This is my top coat of choice for sure.Professional pearls: i would not use this for marbling or techniques that would require your pigments to move and shift, dry and work time will reduce that movement. Don't spray it with alcohol, it degasses great on tumblers with a light torch. From experience fast sets can get an amine blush with alcohol. As far as mold casting, thin molds only as this stuff is lightening fast, pour too deep you might have a flash cure. I can't wait to try this in some high detail coaster molds. This is now my holy grail for top coats, hands down. It also is pretinted blue in one part, which is vital to prevent yellowing. Super easy clean-up with 91% ipa.Considering i poured in lower temps than manufacturer recommends, purposefully introduced bubbles with popsicle stick, and had a lower humidity, this out performed every fast cure I have ever tried.I'd give it 100 stars! Buy it. Try the small bottle first....trust me, your going to go back.
