Hi Jade,
I’m sorry to hear your resin isn’t curing. At this point, it is unlikely to cure. We have a troubleshooting article here that may help you pinpoint the cause of the problem. https://resinobsession.com/resin-frequently-asked-questions/resin-troubleshooting-tips
In the meantime, if your resin is gooey, there is no way to save it. You will need to scrape out of or off your project and start over. If it’s only sticky in a couple of spots, you can recoat with another layer of resin and do okay.
