I have read lots of discussion on the use of acid wash. I would like some details of the application and precautions. I have a product called Milkstone Remover and Acid Rinse. (about $15.00/gal) The label is Phosphoric Acid (75% solution) 56.33%
Other Ingrediants
Surfactant, Dye, Water 43.67%
Do I dilute this futher with water or use as is?
How long do I put it on the metal?
Do I rinse with water and let dry?
Do I need soda in the rinse?
The painters will use PPG epoxy primer. Any precautions there?
We are doing this on rusted sheet metal that will be sandblasted first.
Or, would I be better off getting some Picklex 20?
I would appreciate any thoughts.
Thanks
