We didnt deal with PPG corporate and neither will you. PPGs jobber network is where people like you and I go for paint and supplies. Our local jobber, C.A.R.S., helped us immensely during our project. Here, C.A.R.S. Technical Advisor Keith Anger inputs our color formulas into C.A.R.S. computer for custom mixing. C.A.R.S. will mix and ship custom paints, but please dont call them with technical questions.
