I don't know what was used as a seam sealer on these trucks originally, but there was nothing left on the outside of the cab. On some of the seams inside the cab there was a hard material that I can break off in pieces. Looks like it was originally installed by hand (like putty).
I used seam sealer on every seam on my M38A1, and will do the same on this truck to keep the water from getting between the layers of metal.
