I was watching a show on TV, specifically diesel and in this series they were showing heavy commercial diesel engines being built. The final step for all of these engines was to spray paint them. It looks like all they did was cover the fuel openings with plastic caps and then they sprayed down everything. I know this isn't really related to MBZ's, but I am a diesel fan and thought my fellow MBZ gurus might know?
I figured my 300D would look nice with a purple engine...NOT!!!!!!
