This is a US1000-4 Super Clean Plastic Clean. Before doing any kind of plastic repair, we recommend that you use Super Clean Plastic Cleaner to maximize strength & durability of your repair. Works great at removing stubborn bugs, tar, grease & oil. Unlike other cleaners, Super Clean does not contain mineral spirits, which leaves an oily film causing adhesion problems. It's simple to use; just spray on & wipe off with a clean, lint-free cloth.
