seam sealer vs. body filler in sheetmetal beds

really close to start tearin up the ride for all the body work and some primer. just finished up weldin up the bed sheet metal and trailer tubs and have been told both have advantages & dis-advantages, how say you? please chime in

i second the question slappy, mines fully sheetetaled and tacked in but i havent finished it yet because of the same question thats been killing me, any input, opinions, or advice would be awesome thanx guys

dont use evercoat it cracked out on my bed, try marglass http://www.sjdiscounttools.com/mar01160.html

is that like some sort of fiberglass??

3m fast and firm seam sealer if theres no flex. flows really well and you can feather edge with just laquar thinner.

I use Fusor brand seam sealer, its flexible, paintable, and sandable, so you can make it look just like filler but retain all the qualities of seam sealer so it doesnt crack.

sick, does that need the double tube gun that hooks up to air?? 

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.

No double tube gun, just a regular cauking gun.
