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 |

Ospho website says apply thin coat and let dry 24h before applying paint. (IMG:style_emoticons/default/confused24.gif)
