RR–2381 is used as a corrosion removing and metal conditioning compound which, when diluted with water and applied to metal surfaces, will remove rust from ferrous metal surfaces and provide a slight etching action for ferrous and nonferrous metals to promote the adhesion of paint or corrosion preventives.

RR–2381 is intended for use as a rust remover for ferrous metal parts and as a metal conditioner for ferrous and nonferrous metal parts prior to application of paint and / or corrosion preventatives.

RR–2381 can alternatively be used on aluminum for preparing aluminum parts for painting.

Do not use on zinc, tin and galvanized surfaces.

Add 1 part of the concentrated material as received to 3 parts of water by volume. Use acid resisting steel, earthenware crocks or other suitable mixing tanks. Remove heavy rust by wire brush and heavy grease with a grease solvent before applying the compound.

After proper dilution, apply by brush, rag or sponge. Allow the compound to remain on metal surface about one-half minute. Wipe off residue first with damp rags, then with dry rags. No more than a light film of gray-white coating shall remain before application of paint.
