I don't think the rear end was painted at the factory. The dealership may have plastered it with undercoating but they didn't paint it. The trunk had a splater paint of light grey and either white and green latex or gren and pink splater just can not remember.
Thanks Dave. I'm pretty certain you're right about no paint on differential case from factory. I quess better question would be what paint have people found to most look like the original cast iron look and avoid rusting now.
Thanks David. Great lead. I've been to enough Chevy car shows over the years to see trunk interiors that just don't look "right". My guess they're either painted from spray cans or the painter just mixes up some paint on the fly with some latex in it.
Thanks Allan. Like duh! I bought lots of paint products from Eastwood in the 90"s and just forgot about them. I used their chassis black for my frame plus spray gray, aluma blast, ... for detailing. Thanks again.
The rear axle assemblies were supplied by either Detroit Gear & Axle or Buffalo. They arrived at the assembly plants on pallets as compleete assemblies (drum to drum with the third member) and the entire assembly was painted with a thin coat of black paint.
