So I pressure washed the M-725 yesterday. When I got it, the two giant Red Cross decals on the sides were cracked into a million peices and dulled so bad you can barely see the red cross. I'll probably repaint the whole thing one of these days, but for right now I just wanted to clean it up a bit. So the pressure washer removed all of the decal, except that the adhesive is still on there. What can I use to try to remove this, but not hurt the paint? Is that possible? It still has a little bit of stickiness to it, I'm afraid it will collect dirt, and then I'll have a big brown square, lol.
