Have a glass blasted car in for paint. Needed to apply Ospho for surface light rust that developed. We are trying to determine how to neutralize before epoxy primer goes on.
Instructions say brush off dry powder then wipe with mineral spirits. In another section it says to etch wet with Ospho for 30 minutes then wash down with water. That seems risky due to flash rust. Anyone have experience to recommend which way to go. TIA Terry |

Pick a paint line that you want to use and can get help locally or thru phone. Use what they list on the tds and how they tell you to use it.
