Seam sealer or bonding?

[Softpatch]

Unlike bondo which will hold moister
seam sealer is more of a sealer and is workable like bondo but once set you cant really sand it
pread it on smooth it out let it set and move on
and when dries it has minimal flex and can be painted
it's really wonderful stuff
it's like a 20yr durability.
that's way longer then I'll be around
well maybe not in Arizona but real word application
