GEC, I just saw the post on the Sw9 a few post up this thread. You don't need to remove the entire number to change one digit. Check out Matt Snell's article in the July issue of Model Railroad Hobbyist titled "Speed Bashing." You could use his really fine sand paper method to remove 1 digit and not disturb the paint. You won't find the fine sand paper you need at any big box store, but you need to go to a paint store that specializes in supplying the auto body shops in your area. They carry sand papers with grits all the up to 4000, maybe even higher for use in color sanding fresh paint. I think Matt used 1500 on the model featured in the article, you might try an even finer grit to remove the single digit without damaging the paint underneath.
