Non-Toxic Cement for Plastic can be used in the construction of plastic model kits and is versatile - great for everything from plastic to Styrofoam. DIRECTIONS FOR USE: Preassemble parts without cement to insure proper fit. Trim or file where necessary. When cementing painted or plated parts, scrape away paint or plating from surfaces ot be joined. Apply cement sparingly to one surface and press firmly together. Avoid glue on fingertips, as glue smudged on areas not to be joined cannot be removed. It will also discolor or cloud up clear parts. Do not use on clear parts. Use 3515C Clear Parts Cement.
