Early Body Seam questions.

I was wondering if anyone knows for sure where there was seam sealer used on the early fords. The bed seams, side panels, etc. I started stripping and digging in all those side panel seams but it's hard to tell if they used seam sealer or if what I'm seeing is just old coats of paint.

Thanks, Don

i was wondering the same thing. i did bead seal the whole van with a sealant that i use on aircraft. there is a technique to putting it on that ensures a nice finish after paint

3M makes a nice seam sealer that is fairly easy to use with good results. I just wasn't sure what they did from the factory and want to maintain all the different panel definition when done.
