74 Hang 10 Project

I did get the spring. I went with "Just Suspensions". I got the six leaf with 1" over stock. It sits just a little higher in the back. That was the look I was going for.

I have to keep the car driveable as I am still looking for a place with a larger garage & I don't want to move it in pieces.

I have made a little more progress on the undercarriage. I have been using Eastwoods restoration kit (rust converter,encapsulator,top coat).
Is anyone familar with this? After seeing other restoration projects I am wondering if I should have went with a different product. I still think I would like to apply some sort of truck bed liner for more durability. Any advice would help.
When I do get a bigger work space I plan on pulling the motor & tranny & finishing the undercarriage.
