Many of us have first hand experience with bad rust damage of frames of trucks with double frames, primarily in the northern states. I know of trucks getting new frames due to the rust. I had a truck with a double frame, and I had no evidence of any rust problem. I used to spray WD-40 along the top between the edges, as well as wherever there was a hole punched in one but not the other. Does anyone know of intervention that can be performed before damage gets serious, besides just spraying oil? I already know of at least two places that spray oil. This is for a fifteen year old fire truck.
