Body caulk

I did a search and only found this link:

a question about caulking seams on a hmmwv....

I'm slowly prepping my hmmwv for paint, and I've noticed that several of the seams between body panels are sealed with something that I assume was at one point flexible... it has dried out and is crumbling in places, and I'd like to replace it before painting.... What is this stuff, or what...

I thought I would start a new thread only on body caulking products.

I plan to weld some sheet steel panels together and need to caulk between the welds.

What products do you all recommend for my application?

My dad has been using the 3m heavy bodied (and self leveling depending on the specific use case) for the better part of 40 years and swears by it. I've also been using it for a few years and have yet see it fail (or my dad for that matter). The part number is 08308. It won't let go and stays flexible for a long time, longer then any single part stuff my dad has tried (all the single part stuff I've used has been ok, but it's only been applied for about a year so not nessacarily a good comparison). It is expensive but I trust it not to fail on my for the rest of my life!

Thanks everyone. Anyone know if there are any issues or special prep for Behr paint on or under.
