Paint House in Durham
Kar Color on Hardee St is who I have used for 20 yrs. You can see the place from Hwy 70 at the Geer St exit next to a church. Most there are helpful, some better than others. Last time I purchased acrylic enamel, they had switched to some unknown to me brand of paint and had apparently ditched the old names like RM and Dupont. Lately I have used a paint house from NY that heavily sells on Ebay. I can get code mixed color shipped to the house for less than Kar Color. Raleigh has a paint house as well near downtown. PPG is available at Import Car parts store at Club Blvd and Broad St in Durham as well.
Hope this helps.
