The Stovebolt Site Forums The Parking Lot Panels 'N Burbs Lead seams and bolts

1949 Chevy 3800 panel
While removing all the layers of paint we found two areas on both sides that look to be leaded seams one at the rear where the drip edge ends by the top barn door hinge and one in the front where the drip edge is at top of windshield. Both appear to be done prior to first coat of primer. Is this a factory seam, and what’s the “correct” way to fix cracks in it.
We have uncovered various layers of paint, primer and some areas of body filler in the usual areas but not much.
We have gotten the passenger side down to raw steel and are working on the driver’s side.
New wood floors and bed strips at 113” long has been ordered from Mar-K “thanks Amy & Kevin.
During the floor removal the back strip at the rear of the strips was installed with recessed carriage bolts that were smooth on the top inserted into dimples in the cross end strip where can I get these polished SS to match the new strips
