REFLECTOR: Painting with Awlgrip

Mon Jul 4 12:56:08 CDT 2005

<... used some Aircraft Remover to clean the spray head.  Worked great - 
even cleaned the paint that had been building around the "fan" air 
nozzles ...>
What exactly is this stuff, where do you get it and what does it cost?  
I didn't think there was much of anything better than MEK.  I'll be 
doing some painting in the not to distant future and I'll need all the 
cleaning help I can get.

Thanks ... Jim  S.

PS  I looked at those Mohawk respirators (hoods).  Said hoses (and 
presumably pumps) were available separately but I couldn't find them.  
Anyone got the menu chain for me?
