Youll get alot of opinions on this, but heres mine... 3m has a new 2-part bare metal seam sealer that is awesome, its the same workablitiy as the heavy bodied, but with metal etching properties. Body filler will work, but it needs to be thin, and the metal needs to be competely welded (not just tacked) and any pin holes between tacks will eventually allow moisture under the filler, thats a couple years down the road. Either way its alot of work, good luck.
