1972 Duster Project - Back From The Pasture

You're not kidding. Ours had pretty deep surface rust on the low areas but not rotten. We spent a day or two wire wheeling the **** out of it then painted the rust areas with POR 15, then Raptor liner over that. If you're going to paint it like factory, it's a **** ton more work. We cut a corner with it due to schedule. Still looks great today. Hard as a rock.
Kueneman may have something to chime in with here, not sure what condition their trunk was in.
Wire brushed the **** out of it. Cut a few pieces out that were rotten and welded in new. Flipped it on its side and Kaelyn blasted the areas where we just could not get to metal with the the wire wheel then epoxy primered it and painted it with the car. Oh and the wire brush was a four-inch nodded type running on a 90° grinder not one of those wimpy ones that goes on a drill
