How can I fix a greasy top layer on my resin?

  • Sometimes when resin is left to cure in cold conditions, the surface can develop a greasy film from the amines in the hardener. This film rapidly clogs sandpaper. The best thing to do if you detect this greasiness is wash it with warm water mixed with a small amount of dishwashing detergent. The amines are water soluble and will wash away easily.
