Been researching in circles.....after sand blasting I am looking for a spray/mist on pretreatment that will halt oxidation without the need for further washing on steel/iron prior to zinc powder and powder coating. I have found Bonderite/Henkel 1201 for aluminum. I think Picklex is way over priced and looking at Ospho or locally brewed FlashGuard. My list is limited due to availability and or shipping. Open to other choices that are thin enough to spray.
