cabinet painting

[Chuck W4MIL]

Hi Wayne,

I buy mine at WEST MARINE in Daytona Beach.  For those inland, mail 
order might be the way.  I don't know if ACE hardware has it or not.  
I'm not familiar with the Feds banning the stuff. Closest to you is the 
ships store at Cape Marina in the Port.  We are at the port regularly 
and I always check the ships store for "stuff".............

Hope this helps.

  Hi Chuck,
  Where can you get Zinc Chromate? I thought that the environment police 
had banned it.
