a process for manufacturing a metallized part using the island coating method , including spray depositing a primer layer , basecoat layer , or combined primer / basecoat layer . each layer contains an increased amount of film forming polymer by using liquid co 2 as a supplemental carrier along with a reduced amount of organic solvent carrier thereby reducing waste disposal costs and environmental concerns . further , this modified island coating system can be used to deposit layers of 1 . 5 to 2 . 0 mils thick and maintain the aesthetic properties of the metallizing island coating system at a reduced cost and with minimal variability among parts .
