I have read/heard that the metal finishes on the Broadway stainless cars is a bear to remove which gives me hope the following can be accomplished. I have unlettered cars I wish to decal. These models have been clear-coated from the factory which gives them the slightly golden color shift these cars are infamous for. I'd like to be able to remove the clear coat and not affect the painted metal finish (Alclad?) so I can apply decals and then apply a new clear coat that doesn't create the hue of the original. Can anyone support this as being possible without counting on divine intervention?

I don't have any relevant experience with these, but is it possible that they used a lacquer-based finish? I've heard that brass models were often coated with something like that.

Working with these multi-layer finishes is very tough. AntonioFP45, who posts on Atlasrescueforum and ACmodels, has done the most research and experimentation with metallic finishes, so he is my go-to for advice.
I relettered some Walthers cars, and the best I could do was paint to match the existing finish (mostly), using Alclad, and then re-clear the car.
If you wanted to do a full strip/repaint, you'd get some control over the final color if you wanted the body color to change.

Actually the body color is good, but the clear coat that has been applied gives the car a slight golden hue. That's why I'm hoping it might be possible to remove the clear coat only. These metal paints have a reputation of being rugged as well as fragile which is why I'm hoping someone here (and I'm looking elsewhere of course) has experience with this line of models.  Lyle D |

AntonioFP45 also participates in the Model Railroader forums. His passenger car work and expertise on finishes is tops.

Just an update if it helps anybody. Their earlier cars were nickel plated, the box indicates that. These easily strip with alcohol leaving the nickel plate so glossy you could use it as a mirror except for the surface's curvature. The pain is having to do it multiple times as it's difficult to see what clear coat hasn't been removed yet until the model is dry from the previous attempt.
What I'm curious about next is what clear coat (chemistry?) is going to be a good sealer as well as reduce the sheen so that it approximates stainless steel. I want to be confident the clear coat will bond to this nickel plate. I want to avoid the 'yellowing' the original coat has as well. Any experience and/or recommendations?

Future floor polish is my go-to. It is an acrylic and adheres well to bare metal surfaces. Being an acrylic, it should not yellow, but I have only used it on brass locomotives, so.......
