It's Duplicolor Shift green-purple , they also make a blue purple but I am betting the color shift is not as impressive, that blue purple would probably work well on Yamahas , it's Lacquer just like the Perfect match series colors but $17.95 for a much bigger can, I got a $10.00 rebate from Oreillys so two cans for $25.00 .
I shop every parts store in town except for Napa , they are just ridiculous,. you really have to as they don't stock a lot , Advance had one can of black primer , I needed two so I got the other one from Carquest yesterday , neither had Color shift so that came from Oreillys ..
I was able to get a charge account at Carquest , you can go online at Advance to spend your perks rebate bucks along with online discounts , then pick it up at Advance or Carquest if Advance doesn't have it in stock , the website checks both stores inventory.
