I work from the top whenever I can. I tack a corner then hold the patch
with a screwdriver and tack all corners and high places. If it is a small
hole, I just weld it shut. Make sure you get your mig off the weld as soon
as you see it getting red or you may blow through.

Getting ready to do my first MIG welding - repair of the driver's floor.
Does it make any difference if I attach the patch from the bottom or from
the top? (I'm thinking more about water accumulation than strength.)
I intend to cut a piece from another car that's 1/2" bigger in all
directions than the hole I cut out, so there will be overlap.
