As much as I would like to have a collection Old Yella will be going to a new home. That was the driver for getting it polished. First time it has been washed since I bought it. Getting the left over bits where the gorillas removed the decals took a few hours (and a little swearing)I'm guessing that "Ol' Yella/Greenie" will be rolling down the road to a new owner after you build up "Big Red"? Or are you planning to start an ambulance collection?
Regardless, a bit of polish does make it look a lot nicer.
