I'm having all my body panels media blasted as well as my rear housing. I'm looking for some suggestions on what to apply to the rusty areas after blasting to prevent it from coming back through again. I've heard both good and bad expericnes with Ospho when used on restorations. Will Silver Bullet do the job I'm looking for? How about Por15? Looking for something that will work with standard primer/paint coating processes. Thoughts/expericnes anyone?
