Aluma Treat is a specially designed product used as an additive when preparing aluminum for painting. Aluminum parts form a natural oxide film which prevents them from accepting an acid etch. Aluma Treat, which contains a source of fluoride, will remove this oxide film and allow the acid solution to react with the aluminum part. A proper etch is a very important part of paint adhesion for aluminum. Aluma Treat will also tie up any free aluminum and prevent it from interfering with the phosphating reaction on steel.
