From Wexrocks ..
Ten years ago, I tracked down the company that has the original formulas from Glastron for metal flake mixes. I thought all along that I had found it here, but apparently I did not. Getting ready to do some projects with my Scimitar had me looking for that info, so I searched it here and on other groups, and quickly realized this must not be where/how I originally found it. So, I began digging for the samples and info they had sent me 10 years ago, and, I found it! Spoke to them today, and placed a large order of flake and accompanying products for my projects. They have formulas and flake for most colors from 72 to 82. If you call, ask to speak to Allan, he is the flake master, and he gave me his blessing to share this info with all of you. Admins please post this anywhere you feel it will be useful to users? enjoy! They do have a website, but very little info there regarding the metal flake.
