Wanting to expand my fleet of Rutland hoppers I ended up buying a second 3 car set. I needed to change out some numbers. I purchased a Paasche air eraser. It comes with a jar of fine grit aluminum oxide. I was basically removing just one number. I masked off as close as I could get to the number I was removing. A few blasts and it was easily removed. It dulled the paint underneath a bit. But a pass of clear gloss brought it back. Just remove the tape before hitting it with gloss so you don’t end up with a sharp edge. Use a number close to the size of what you masked off. Then clear back over it after you apply the new decal. Even if it ended up a little dull underneath the new number should cover it.
They can be had for about $60.00 with the small jar of grit. If you already have an airbrush and compressor it’s a good buy. I wasn’t doing an engine and if the results went south it was a matter of matching black on something that was going to be weathered anyways. Yellow as mentioned are all over the place for correct prototype colors. If you go this route. Use about 35 psi. and work slowly on something for practice.
