Firewall to floor pans and but welding connections etc..?

Firewall to floor pans and but welding connections etc..?
OK, so I am going to do my drivers side firewall to floor, and also the drivers side long floor if it looks like it needs it. I am also going to change out the frame extensions.
My question is about the welds and the connection points, to do it right should I but weld the seams? I want it to look good underneath the car and I think any overlap would leave a place for rust to hide again.
And when I buy the new pieces will they have a folded lip on the side that welds to the inner rocker panel and the kick panel area?
I would really like to see some pics of this being done, so if you have any can I see?

Right or wrong I over lap welded my pans. On the underneath with what gap I had I hammered it tight to the section it was welded to and I then put roofing stop leak sealer on the joints to keep any moister out. I then painted all that over with the truck bed coating.
Some people me balk at the idea of using roofing stop leak sealer on a car, but it has lasted years on my house roof around the chimney and pipes with no problems. Besides, a gallon of roof sealer was $13 and it is ton cheaper then using auto seam sealer at $5-6 for a small tube of the stuff. I also used it on all seams inside and it was paintable a well.

Here is my left floor welded and done with the roofing stop leak sealer. I just used the sealer on all the welded joints inside and underneath.
Right side patch as I wanted to keep as much original metal as possible
The underneath is done similar.

I am a fan of butt welding panels together, but imo it is totally not needed for floor pans. It will take far more time than is worth it for the results butt welding (here) generates.
If you seal the seams with a good grade seam sealer rust will not be an issue worth mention.
Ooops, posted this on wrong account!!!!
I was trippin, Jim posted the same thing I did.... (duh)...

Well, I want to try to restore the underside of the car over time, if I touch anything it must end up looking professional and correct. I really want to end up with a car that is worthy of crawling under.
What do the restoration shops do? Do they just go ahead and replace with a one piece floorpan? And if so, how do they connect to the firewall to floorpan steel?

So in reality they overlapped and rosette & stitch welded that pan in place?
I wonder how they handled the underside air space between the panels? Do they weld those on the underside also to make it tight or just seam seal it?
I have often thought of attempting a one piece pan, but I will not know until I get the goo off of the underside to make the determination. My big concern is the firewall to floor pan piece, it would show up in the front wheel well and I dont want to see it every time I am looking at the car with the wheels turned, in reality the overlap may be stronger and less brittle than a but weld....
