I was scraping crud from under my 46 1/2 ton front end. Under the thick crud was shiny black paint. Under that appears to be very bright orange paint. This was exposed with just a putty knife, no sanding. The orange is on the frame, shocks and inner fenders. I'm assuming the factory never used orange primer - so it looks like sometime in the truck's history it was painted orange! The underside was always black wasn't it? Thanks.
