Re: Tri-Sodium Phosphate
Not the same at all. Klean Strip Prep and Etch is "phosphoric acid" buy it at the box store. cost's way less than brands like Ospho sold at auto paint supplies.
If I need to do a few pieces of hardware quickly, after media blasting I heat some acid in a Pyrex container or even a SS soup ladle clamped in my vice to around 130* F for a few minutes checking the results from time to time. Rince in hot water, dry and treat with Boeshield.
Works in a pinch.
There was a good how to on the WWW by a Mustange guy and I can not seem to find it right now.
