working on an old Chevy K-30 (1-1/4T 4x4) squarebody pickup..surplus ex-military truck..engine swop (from a 6.2L diesel to a 350/4BL) then unbolted and lifted the bed off, stripped the frame; sandblasted and painted the frame,suspension and rear axle with black acrylic enamel,-added a bit too much isocyanate hardener with the paint..gawd I hate working with that stuff but it does give good results. cleaned up the mess afterwards,put everything away..that's enough for one day..wiring and new radiator tomorrow if I can find the gumption
