Got a little cautionary tale about redi strip, had a few parts done there & thought I was home free, You must get all the water out of the crevices used low fame torch for this, then i flooded it with por15 (really messy task & you really have no idea if you coated everything) then did all my normal prep & paint stuff. everything semed fine, finished the top of the hood last .Flipped it over to do something before installing it & found rust bubbles in a couple of places that were two or three layers, granted my car was a rust bucket, ended up scrapping that hood & workin a backup, heres what I've learned since.
Without an ecoat dip after the stripping there is no protection for the now raw metal in there the only way to be sure is to skin the hood, a major undertaking & a chance of messin up a decent hood.
So if your not gonna ecoat I would not redistrip anything thats layered(which unfortunatly is most parts on our cars.
Clean what you can, use some kind of rust treatment & really flood it in there & you'll probably be better off the a acid dip without ecoat!
Not a pro but messed with a lot of rust(well still am on the 74 now) over the last few years. I would not dip another part without ecoat ever! Rich.
