Source for Phosphoric acid for parking

kozeb · July 23, 2009, 10:26

I am new to parkerizing. I bought a park kit and used it with good results. Now, I would like to make my own solution and I am having trouble finding a gal of phosphric acid. There is plenty of muratic acid in the hardware stores but no phosphoric. Any Ideas? I read somewhere concrete ecthing acid was phophoric but?
Thanks

Tough to find. You can get it online, but shipping is very high.

You might try going to a Home Depot or Lowe's and look in the paint section for a product called Jasco's Prep and Primer. It's a phosphoric acid solution, but they also add some glycols for thickening, so it smells weird. I've used it before and it does work, but you have to do some math to correct for the lower concentration of the acid in the Prep & Primer.

I've heard of people going to their local Coke or Pepsi bottler and buying gallons at a time, but when I called our local bottler they told me "no way". YMMV.

Try "Phospho" from Home Depot. It is an etching solution and sold in the plumbing dept.

Try getting 'kleen strip' phosphoric acid solution from Lowe's , an 'Ace Hardware' or try an
OSH-Orchard Supply hardware.

My recipe is-
'0000 steel wool pad

Molybdenum powder or is it manganese?-ANYWAY, the black powder out od 2-4 dead Alkaline 'D' batteries

Kleen Strip acid-
