I sand, grind, neutralize or whatever on the inside when the panel is off. I'll do something to finish and seal the inside of a repaired panel, even if I have to make an access panel to get at it. On the absolutely impossible places, I use the weld thru primer. If you can't get anything over it, doesn't really matter what kind of joint you have, it's gonna rust!!!!! When all else fails on the really impossible places, a can of spray on undercoating with a long plastic nozzle sprayed through an access hole is better then nothing.... Also, on my flange joints, I flange the topside of the joint in so that there is not an open lip facing up on the overlap to allow moisture to accumulate.... (Hope that makes sense, I could show you a whole lot better then I can write!!!!)
