For the pan replacement or patches, are you guys doing over lap welds or butt welds? I was planning on doing a butt weld, but I have 16g sheet and I am starting to think more along the lines of just fitting in a patch and doing an overlap. The reason I wanted to do the butt weld was because I am going carpet less and doing Monstaliner after everything is repaired. The thought of having a big noticeable patch bothers me though and the reason I wanted to do the butt weld...but may be easier to just say screw it and over lap a patch?

Overlap will be easier. Trying to get patches to butt-up perfectly will be meticulous.

Friend of mine had his done a few years ago by a local 4-wheeling shop. He bought replacement pans ready made, and the shop welded them in. They were designed to be lapped, not butted.

You'd spend a looooong time getting the fit right for a butt weld, and it wouldn't be as strong unless you are a very experienced and skilled welder.

Overlap weld. Then use some body filler to feather out the seam after grinding smooth.

overlap weld them, it's much stronger

I work in a Mustang resto shop, and we offer either. Butt welding looks super clean, but I charge a HECK of a lot more for it. Extremely time consuming & tedious work. If you're OCD and have the skills, go for it. But for most Jeepers, that "perfect" invisible repair just isn't that important. Drill your 3/8 holes every 3-4 inches, burn in with some nice rosettes, prime, seam-seal, paint... and roll on down the road.

I went full OCD on mine and did butt weld patches. Turned out great, but as everyone above says it's a giant pain in the ***. To do it again, I'd just overlap.

Im going to overlap. I got the 16 gauge cut to fit...but its a pain to bend and work into shape of the floor contour, so I have someone giving me some 20 gauge sheet instead that I will now bend and use. Im going to spray some weldable primer below along the edges and frame, and then when its over I will prime again, and then seam seal. Should I seam seal before I do the chassis saver / por-15 or do it first and then seam seal? Final is the bed liner.

i would seam seal before doing chassis save / por-15. I would actually seam seal before priming even. In my experience, seam sealer sticks best to bare metal.
