To answer the orig. question, use automotive seam sealer, it's availabe in a tube or you can get it in brush form as well, use acid brush to apply.
I would'nt think the item be fully welded, not required and you stand a better chance of undercutting the material/unibody in the process.

Well before welding you must first know how to weld.

YES.....but dont expect the performance you're thinking.......it's best used when replacing quarter panels and such.....not directly exposed weldments.

They claim it's for weld-through applications.

I would use what the factory uses and what most professionals would use, flexible/brushable automotive seam sealer. $8 at the paint supply, but once you open it, you will have to toss it.
As far as the stiffeners, I've seem people do it both ways and it seems that stitch welds add a bunch of stress points if used between the suspension mount points (under the seats). Just as the OP stated, they tend to crack a weld and indeed it does seem to limit them to one weld. However, IMHO it seems that the couple that I've talked too who welded the entire length, plus use rosette weld on the sides, AND continue the stiffeners past the front and rear suspension points don't have the cracks or tear issues at all.
I'd say leave it, but check it often. If you get it all twisted up, you are likely to develop cracks. I'd imagine you'd have to get pretty crazy with it though. The guys I know the added them aren't the most technical wheelers if you know what I mean.
