I have had the same problems with flash rust after using dupont metal prep. It seems like a sometimes thing. I have started wiping them dry with cotton rags/blowing them with the air hose/setting them in the sun. I also have been mixing the metal prep stronger. I haven't had the problem recently so maybe one of those things is a fix.
Did your flash rust occur almost immediatly, like within seconds? Mine seemed to. I wasn't even sure it was rust, maybe just a gold color. It was dark and I had poor lighting.
