Testors Non-Toxic Plastic Cement 5/8 Ounce Carded Package Instructions: 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 to 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.
