<VV> removing overspray from plastic

Harry  said: <snip> I have always used 0000 steel wool and Prep sol to remove 
 overspray from GLASS. Works great. HOWEVER I tried this with a rear view  
mirror (not corvair) and it ruined it. <unsnip>

Craig replys:
Might have been one of those mirrors that has the reflective material on  the 
surface, rather than the back of the glass.  Those Vitaloni "blue-tint"  
mirrors of the 80's are an example.
Thanks for the tip.  I've never worked with prep  sol.
