Any opinions on filling the body seams like the back panel to roof seam and the seams on the upper cowl. Body filler or weld?
I think you have to weld, these cabs flex, and you WILL get a crack otherwise. you don't have to fill it completely, but a good tack every 4-6 inches at least.
Weld it up side to side, use a Bern-Z-Omatic torch and a wire brush to remove the original seam sealer first. Finish it off for that slick-az look. LOL

I second this. I welded mine solid, but the first couple of welds were ugly because the fumes from the original seam sealer raised hell on the shielding gas. Once I cleaned out wiht a wire wheel and a propane torch it went smoothly. I welded the whole seam end to end, but I think Randy Jack's suggestion of tacking is probably more than sufficient. That won't flex...
Isn't seam sealer a rubbery substance? I wouldn't think you could finish sand and paint it. What product are you refering to?
Seam sealer comes in various forms...the one you want is one of those that is a 2-part product. I use a 3M sealer, 2-part, that sets up in less than 10 minutes and has a consistency of a hockey puck when cured. This product can be sanded and painted...the only issue I have with it is that the expansion rate is different than the paint so I always leave a little space on top of the sealer to add a thin coat of body filler to finish off the repair.
