I just got my new batch of resin and hardener and when I was mixing it didn’t feel as thick as usual. I even double checked to see if maybe I had accidentally added 20 ounces of resin instead of 10 of resin and 10 of hardener, but I had not made a mistake. Anyway, my project is now gooey and won’t cure. The whoops forum here says I should remove the uncured resin before reresining. But I don’t know how to do that? It talks about sanding but how can you sand something gooey? Can you explain how to remove uncured resin? Thanks
