Fluid for Armstrong lever shocks

[Scott.Mackay@SEMATECH.Org]

     Hi All,
     
     Just putting together the new rear suspension and had a question about the 
     lever shocks.  
     
     I want to experiment increasing the resistance by increasing the fluid 
     viscosity as one does to tune fork shocks on motorX bikes.  I know, I 
know, 
     I can just sent my shocks off to Apple for the uprated versions, but short 
     of spending the $50+ per shock, I thought I'd give this a try as mine are 
     still in good shape.
     
     Does anyone know the type of fluid and viscosity that was originally in 
     them?  I'm guessing something like a 10W.  The Armstrong bottle does not 
     appear to have the info on it.
     
     Also, my shocks (I believe they are original) are painted a bright copper 
     color (very similar to a bright, newly minted penny).  Has anyone seen 
this 
     color before in a spray can?  At this point I'm reduced to the local hobby 
     shop for some model paint.
     
     Thanks,
