Recycling Rusty Fasteners

If I'm not mistaken, according to the company literature, it does not require a neutralizer. I don't rinse with water and have never had a problem in ten years. However, it could not hurt anything to do so.
I'll repeat the company info here is case it was missed in post #5:

"After the Ospho reacts with the steel surface it is completely neutralized and does not leave behind any film or deposits that might interfere with subsequent primer/topcoats."

Here is a fact. Different epoxy primers have different chemical makeups. Trust me, IF Ospho is not properly neutalized there can possibly be a reaction and even months down the road. I'm no chemist and the best explainations I have received were from Southern Polyurethanes experts. Give them a call for a good explanation as to why such can happen.
