Paint stripping without a D/A

SPI will say this also: IF treating metal with Ospho, be sure to neutralize it with water before appling their epoxy primer, You can get a reaction. I have used Ospho for maybe 7-8 years and works great for me especially on pitted metal or metal that I can not sand down to clean.

That's interesting because I didn't use water afterwards. It did sit for several days until I sprayed it with an epoxy primer that is used on aircraft, but I scuffed the surface with a green scotchbrite pad, then washed with a solvent before primer. no rust issues yet......crossing my fingers. The primer I used has the best material for corrosion prevention.
