hey enrisan, I should have read this one all the way through before Pming you back, when it came to cleaning up the ones i had a pocket knife or even better, an exacto knife is really all you need for fixing things up. Hell, mine had to be cut in half to put more foam rubber mix in so the things would fit my freakishly large calves, and the original detailing in the back where Adam and I cut it was restored using just the knife.
using the knife will also cut down on the amount of particulates you're breathing in.
Like i said in the PM though (this is just for general knowledge in case someone else has this question down he road), 3M makes a rubberised undercoat aerosol spray mainly used for pick up truck beds, i was able to patch a pretty big hole i put in my right shin with that and a little scrap of rubber i cut off from the inside of the shin that i glues over the hole initially.
