Oxalic Acid in Type II Anodize

Does adding oxalic acid to Type II (not Type III) anodize solution have any advantages or disadvantages?

YES, INSTEAD OF ANODIZING AT 18 TO 20 DEG. C. YOU CAN ANODIZE AT ABOUT 26 TO 28 DEG. C. WITHOUT SACRIFICING THE QUALITY OF ANODIZING, KEEPING ALL OTHER CONDITIONS OF ANODIZING SAME, SAVING ON THE ENERGY COST FOR COOLING.
