Henkel developed Alodine 1132 coating with the convenient Touch-N-Prep applicator pen to provide a clean, easy-to-use method of repairing conversion coatings on aircraft and aircraft part surfaces. The unique Alodine 1132 Touch-N-Prep no-rinse conversion coating effectively repairs bare aluminum substrates to prevent corrosion. It does not require rinsing and can be air-dried or force-dried with hot air. - The high-density acrylic tip of the Touch-N-Prep pen can be modified with a single-edge razor blade to form any shape. The design of the Touch-N-Prep pen allows repair of hard-to-reach places or the underside of aircraft. This new application method controls the amount of coating applied to the surface. Use Alodine 1132 Touch-N-Prep sparingly - a little goes a long way.
