I am considering painting my 68 Grotto Blue because Grecian green just doesn't do it for me. Has anyone here had thier Nova painted Grotto Blue lately? If so how easy or difficult was it to get the correct color and how did you get it? I contacted PPG regarding a part number for this color if available and they said that the distributor needed to call an 800 number to get the formulation to make the paint. Has anyone gone through this process and has a part number or formulation for it already? I'm a newbe when it comes to the painting aspect of restoration and any help is appreciated. Thanks.
