More progress from this weekend. I started by degreasing and scrubbing the underside of the car for 3 hours. Then, my son and I fabbed up bucket seat mount plates from more 4130 plate and welded them in. Lastly, I was able to get etching primer on the remaining bare metal and then painted the underside. I used Eastwood rust converter on the surface rust and then coated the rest with Eastwood extreme chassis black satin. You can tell I’m not a painter because I figured the dust mask was the only safety gear I needed LOL.
