On box tube truck beds I've welded up over the years I followed a similar plan of drilling holes into any closed compartments and filling them with oil and then draining the oil out. Seamed to have worked, the body on my old plow truck is 30 years old. On the platform bed for my C60S did a similar thing but put plugs in holes, couple of years later went to renew the oil coating when unscrewed the first plug water ran out. One of my welds must have had a leak on the top side. Any way removed all the plugs blew out the closed sections, then filled the closed tube with oil again. Drained again an left the plugs out, since then every couple years use a compressed air syphon gun to blow oil through.

Great thread enjoyable to read.

I think the risk with oil is that it may leak out and form a nice dark stain on your matt paint (unless you use semi or gloss). Filling and shaking with POR would fix this. I wonder why there is no POR type paint that will take a final coat. You'd think the manufacturers would expect much of their market would want to do exactly that.
