My experience "blasting" is not important, what is important is my experience in rust removal and I'd say I have a fair bit of that! So you're a professional blaster? Great! Would you make the statement that blasting will remove every minute particle of rust? Didn't think so.

Even if there is any small amount of rust left it will be converted and inert. 5 years no issues. Doug Me too. Was taught that a long time ago. What I use - from Google: The shop I frequent uses Cromax products (formerly DuPont). 5717S etching solution and 5718S neutralizer. The 5717S is a concentrate that is diluted in water and scrubbed via Scotchbrite and rinsed off. The 5718S is then applied full strength and rinsed off. 67 Coronet 500 9.610 @ 139.20 mph 67 Coronet 500 (street car) 14.82 @ 94 mph 69 GTX (clone) - build in progress......
