stripping a patina Duster hood

so i waited overnight and the ospho was dry, i reapplied the ospho and let it sit for 20 min and made sure it did not dry, i then scrubbed the **** out of the hood with a red scotchbrite to make sure i got everything moving and then i did two heavy scrubbs with Dawn and warm water followed by a long rinse with the garden hose.
i then watched my hood flash rust before my eyes, i got to admit im not sure the ospho was worth it, i now have to take off all the surface rust off both sides of my hood... i already have many hours getting it to this point but it is what it is, tomorrow will be epoxy time followed by 2k high build... i guess if it was easy it wouldnt be so gratifying when we finally turn the key...Rich
