MF Plastic Hardener can be added to any liquid plastic to make harder/stiffer baits. For best performance, liquid hardener should be added before plastic is heated. We recommended starting with a ratio of 1 tablespoon of hardener per cup of plastic. A mix of up to 1 part hardener to 2 parts plastic can be used to make very stiff baits.
