Rebar, He is definitely seriously disabled.. He cant see through glass, cant read normal print, cant see color, can't drive any vehicle with a windshield, can't use a computer, cant watch TV or movies, Desolidifed villains are invisible to him, etc etc... His ranged sense of touch is overwhelmed by the same things that touch would be so most damage shield characters get a DCV bonus vs him... A GM may quibble about how disadvantaging it is, but it's pretty major. Alot more major than most complications.
