So much for the first weld - it was rubbish I tell you! Found a bunch of pinholes after applying primer. Had to go back and re-weld until all the pinholes were gone. Turning the power down on the welder helped too.
It doesn't look like I'll have to cut the rain chanel on the driver's side?
And, as expected, found more rust and fiberglass in both rockers.
Doesn't look too bad though, I might be able to get away with patches instead of replacing the whole thing. (it seems for now anyway) The journey continues...
