I'm making my own fender wells currently just stitch welding in. I was wondering what I should use to fill the seem. Specifically between stock inner body and the wells since there's a million little bends and it's super thin.

If there's nothing good I'll mig them in later but I'm using FCAW and getting a bead going on the lowest setting risks blowing through.

I used paintable seam sealer in a caulking tube from napa. Forget the part number but its a white tube with green writing. works slick, and dries in minutes. Then I coated the underneath with Flex Seal, also a great product.

It looks like Napa doesn't carry it in my store.
I'm going to try Loctite S30 roof/flashing sealer. It's flexible and designed for metal. It's polyurethane which I read to use elsewhere.

Unless someone thinks that's a bad idea :)

I'm in the middle of the same thing, I am using Eastwood brush on seam sealer. Really thick, but brush able. Which is nice

Lets see pics of these wheel wells

I used PL S30 poly sealer to seal the perimeter of my unibody stiffener plates. Just let it cure for several days before painting and you should be good to go.

Awesome thanks,
The parts I sealed a couple weeks ago look great, was still unsure if it would endure so I definitely appreciate the input.
