ford gpa g504

Everyone,

I am continuing work on the body and we (the welder and I) have hit a snag. There is an area on the drivers side up against the hull (where the side hull meets the bottom hull side) that we are replacing. The problem is that when we put the hull back, it will be impossible to sandblast or paint this area (which includes the underside of the floor piece and the structural support for the floor. We cannot sandblast it now as it would be too difficult to transport to a sandblaster and then paint and California does not allow portable sandblasting equipment used outside.

The body has already been sandblasted once and currently unpainted. My options are to treat the area with phosporic acid and then neutralize the acid and paint the area and then weld the hull pieces in place and this area becomes inaccessible. What have others done to try and prevent future corrosion? I am sure that they must have dipped the entire finished hull is some kind of metal treatment fluid and then dipped in paint to finish.

Thanks for your help,

Donovan

Donovan can you put a picture with it or a drawing?
General when i meet a part wich is to be replaced and later almost impossible to reach.
I first clean it with solvent ,rubb it with sandpaper,primer and paint it. [not the edges ].
Weld it in and clean it again primer and paint it again with a air spray gun.
If it is a place difficult to reach I put in special coating like waxoil from shell or valvoline amber coating to keep it from rusting out again.
