no, it means only that you must watch when to stop.
as for hands, all orange stuff goes off perfectly. trigger fingers were golden on my figures, they are chrome now. all that is only about orange color, not red blood itself. to achieve an "endo left fingers in holes" effect you must paint the "flesh" into black to mix it with the glove. i still didn't do it as my black paint is totally dry, and it's not easy for me to by one, i have to purchase it from civilized areas of this planet.
1) i got a separate body and two complete figures as my first purchases.
a body had least amount of blood - i mean red paint, not orange. two complete figures from one seller, from one stock were a) a little more bloody than a nude body and b) a little more bloody than previous figure.
2) all in all there is a lot more chrome on this figure than on MMS117 endoarm. everything will be fine with rubbing the orange stuff off, just don't be too persistent or you could damage the chrome. one of my full BD heads now has a little too much rubber upper part, i'd like it to be a little shinier. i'll achieve it on other full BD heads.
nice thing is you can safely remove that orange gel from skin, turning it into pale pink damage.
3) you don't see the chrome "just fine" on a figure out of the box. you see bronze/gold. that is due to transparent orange layer some dumb HT daltonian used to spoil all DX13 figures.
