Rebuilding Rear Seat Frame - Part 1

What started as a simple 2 hour task of replacing petrified seat webbing is turning out to be a two weekend long project! Having lost their elasticity decades ago, the webbings for the rear seat frame were stiff and crumbled to the touch. Replacing them is simple enough as the seat webbing (or Pirelli webbing) is widely used by the furniture and upholstery industry, and therefore easily attainable. Upon removing the rear seat however, I discovered some minor rust spots on the seat frame and decided to take the opportunity to address those while I had everything apart.

The preparation process involved removing the entire rear seat frame from the Volvo, removing all 4 rusty retainers so that they could be rust treated separately with the rotary tool, sanding away all rust flakes, and sanding down the smooth paint to provide a coarse surface for the rust preventative paint to adhere to.

Next, the seat frame was cleaned and degreased with Marine Clean, followed by an application of Metal Ready on bare metal to chemically etch the surface for proper adhesion of the rust preventative paint. Two coats of POR-15 rust preventative paint later, and this seat frame should not rust again ... ever.

As I did not have enough time to complete the rebuild, I'll be working on fabricating the new seat webbing and reinstalling the rear seats next weekend.
