    Does anyone know the exact year that GM began using the Galvanized sheetmetal?

    I'd like to find a new cab & bed for my '75 K20

    I think if you check the FAQ here you will find your answers. Like 88 or something I think. I remember I was dissatisfied because my '86 was not.

    Don't know what years but I would like to know what parts would be galvanized. I have an 89 so just curious.

    Happy Trails

    As I recalled from somewhere, it was in the mid 80s - maybe that's totally incorrect though....

    I believe it was the "tub" or body as some call it. Didn't appear it was fenders, tailgates, doors, etc. Religious rinsing of the truck, no matter location, should keep rust at bay. Painting hidden surfaces won't hurt either..personally I'm modifying semi-truck mud flaps for the rear wheel wells, to be bolted in using the factory bolts, but covering the opening in the front that allows mud to be thrown into the cracks and such near the rocker panels and seat belt anchoring points. My '83 was thoroughly rusted out there, a shield to keep mud from even getting that far should stop it from happening again. May do the same in the rear portion of the wheelwells, to keep it from throwing crap into the hinge area for the tailgate.

    I agree with you about painting hidden surfaces, but even then, moisture (water) can get anywhere - causing rust.

    My truck is dying of body cancer right now - and I'm hoping to remedy that situation anyway I can.

    I made a tool that attached to the end of a garden hose to spray up inside the holes above the bed wheelwells (cut down on some of the trapped mud & sand) but - my truck is still rusting out in there...

    I made sure to buy POR-15 and thats what I am going to use. I have heard nothing but great reviews of its toughness. I think more than anything, salted east coast roads, and caked on mud, are the worst culprits..although the K5's bed doesn't do very well by design...one place people forget is the inside of the bumper..they are not chromed, and thus rust from the inside out.

    i wouldn't recomend welding the galvanized sheetmetal either, it gives off cyinide(sp?) gas when you weld it.
