Anyone recall using Radocy Zinc Phosphate Parkerizing solution? I used to buy it thru takedown guides @ http://www.takedownguides.com, which is no longer a live link. I still have a 1/2 gallon left in a gallon bottle, but it's been around a long time and likely would need to be tested on something to see if it's still good.
I recently started searching around for it but no longer see it.
Anyone been Parking with a liquid zinc and care to share the maker name?
Thx
