Hi Alan,
What colors do you need? You can't buy PPG Concept in Canada any more, the solvent base paints are no longer legal. I'm sure I could have Kevin bring one of his tutor parts over (I'm assuming you need the paint for the tutor) and match the color in the PPG Omni system. Omni is still solvent based, but it's VOC compliant. Otherwise you have to use the new water borne paints and they are a pain in the butt (and very expensive). I have a complete Omni system, so even though a paint store will be unlikely to do a custom match in omni for you, I can do it if you need.
