I installed new rear glass, door glass and vent windows. I did some searching online and found some good tutorials on how to replace them myself. With some help from my little ones, I got the glass replaced. I also installed new interior door panels, hood emblems and upgraded to black rear tailgate letter decals. I installed a fresh set of tires, beauty rings and a matching set of original 52 Chevrolet hubcaps.
To restore the paint and treat any surface rust I used a CLR (Calcium, lime, rust remover) half and half with water and scrubbed the whole truck with a 3M scotch-brite pad.
The front bumper splash apron was a pretty awesome. Under all that surface rust are these interesting looking brass welds and original "Sun Beige" color under the green. Evidence from back in the 70's.
I used a Clay Bar Kit and went over the whole truck, then by hand I used Complete Compound, then Polish, and then Wax. Three full days of hand buffing later and it turned out great!
