Does anyone else ever think....
that they are over their head building their cars? When I first got my plymouth I thought it would be easy or easier than its turning out. But as I sanded down the body started finding rust holes through the skin, they are small but still annoying. And know that I am tearing the interior apart I am finding out that the floor pan is rusted to hell.
I guess I should have expected this but its still pisses me off that I know have to replace the whole floor pan, which brings me to my next questions for all you great minds out there.
1. What guage metal should I use for the replacement pans?
2. Should I overlap the welds or butt weld them? And what precausons should I take to keep the welds from rusting again? I have found a few forum sites that mention this, but no one seems to agree on how to weld it. Some say butt weld as if you over lap it will rust out. Others say as long as you clean the overlap to bare metal and seal up the welds top and bottom and use seam sealer it will be fine. I am more confused now than ever on replacing the floor pan.

Sorry for my rambling just got to get it out before I do something stupid like selling the car.

Thanks for the help and listening to my b&$chin and moaning.
