So your RR fleet looks a little worn - and dirty. Maybe that’s the look you want or maybe that’s the look that is easiest to maintain. Here’s a suggestion that has worked for me and others.
What has kept the fleet of hundreds of rolling stock looking new running in the Living Desert sun is to spray the car and loco bodies with Pledge spray wax. Not too much, just a light spray and wipe off – some Q TIPS work well among the steam engine fittings and the diesels horns and window corners. Improvement in appearance? There’s nothing like the shine on the FA and F3 passenger locos and the cars – especially the ones imitating the stainless bodies. The steamers black bodies look new again.
Our trains at home get the same periodic treatment. The application lasts at least a month plus for those rolling stock remaining outside with a vinyl cover. One disadvantage is it may attract dust in your locale if there are regular winds. There has been no damage to the plastic bodies and that’s over five years of use on my layout and at the desert display.
Excess? In the Living Desert environment of paid attendees seeing the myriad of operating trains, they want to see that we take care of what is obviously our responsibility. Many of the locos --and passenger trains, for that matter – are donated by the guests and they want to know they are cared for. It is difficult to present weathering as a feature in this setting unless is very purposeful in appearance.
Take the Pledge!
