QuikPlastik Epoxy Putty Stick is a hand-kneadable, fast-setting polymer compound for permanent repairs to most major plastic types. It does not adhere to polyethylene, polypropylene and some other plastics. When unsure of product type, an adhesion test will confirm suitability. QuikPlastik also bonds to metal, wood, glass and masonry. It comes in a handy "Tootsie-roll" form with the curing agent encapsulated in the contrasting color base material.
