I just took the lettering off two Vanderbilt, a box and an axiliary tender last night an d relettered them today. I used this llight blue stuff in a bottle. It had a mild abrasive and after letting it soak for about 15 minutes I used a Q- Tip to ( in a circular motion ) lightly rub the lettering off. Does leave a slight gloss spot but after setting new letters,some dull coat ( Flat or simi Flat ) will seal and even out the rest of the decal so only the lettering shows. Good Luck
