This is on a Nissan 240sx.
Rocker panels are somewhat like this
I found this on google. WHat is the method of attack? My thoughts would be stop the RUST as in and find a side skirt to put over it. I dont think you can buy rocker panel replacements.
Then you have the normal rear wheel well rust, its forming at the 12 o clock spot and at the 3 o clock, for this i assume you just cut off the wheel well and re-weld a sheet of metal and repaint. The wheel well is still solid and not rusted thru completely its surface rust plus some.
I dont have a picture of it. nothing shows up on google.
Lastly is the strut tower rust. Guy looks like he did a decent job stoping the problem. Sealed up the seems and welded some of it.
Would all this be common method of attack? Or is there other body shop methods? Debating on buying a car and doing this stuff at home, paying a shop to do some.
