Gardo Etch 8315/8319 is able to conceal surface die lines and minor scratches without a high aluminum removal rate. Lowers temperature, reduces time, and greatly reduces sludge generation, when compared to alkaline type etch products.*Denotes Gardo Etch 8319* 25−45 g/lFree Fluoride 90−120°F Drum*, ToteGardoClean T 160 Economical powdered etch which produces a matte finish.
