The Optimum Opti Dual Pro Applicator is a double-sided applicator designed to make application of Optimum's coating and spray sealant effortless. With its dual sides, one for application of Opti-Coat 2.0 and the other for Opti-Seal, this one applicator not only takes the place of two separate applicators, but it does a better job too! The Optimum Opti Dual Pro Applicator is slotted between the two layers to ensure it doesn't slip out of your hand while in use. The Optimum Opti Dual Pro Applicator features two sides, each with their own intended use. The uber soft foam side features 100 pores per square inch and is designed for application of Opti-Seal or other WOWA (wipe on walk away) spray sealants. The high density neoprene side is designed for application of Optimum Opti-Coat 2.0, a permanent paint coating. Both products are designed to be applied extremely thin and the Opti Dual Pro Applicator ensures no product is wasted. For the application of Opti-Seal, spray directly onto the uber soft foam side and spread on the exterior surfaces of your vehicle. For the application of Opti-Coat 2.0, dispense directly from the syringe to form an X pattern on the high density neoprene side and apply to all surfaces to be coated.
