Thanks! I think I've done everything I can to prevent rust on this car.. Luckily this is a pretty dry place and it'll never see bad weather again so it should last my lifetime!
I have went a little OCD and puttied all the grind marks and rust pits so it'll be a seamless repair once I paint under it. I also got the torque box in and yet another coat of epoxy on it. I will high build primer the bottom side where needed and sand it smooth when it comes time for paint (factory look)
Here's some more pics!
Painted black in behind the torque box.
Ground off epoxy where needed and applied weld thru primer.
Puttied where needed.
Welded up five holes where it appeared to have an electric fuel pump at one point.
