## to completely assembled motor vehicles or to parts that are not yet on a completely assembled vehicle to correct damage or imperfections in the coating. The curing of the coatings applied in these operations is accomplished at a lower temperature than used for curing primer-surfacer and topcoat. This lower temperature cure avoids the need to send parts that are not yet on a completely assembled vehicle through the same type ofcuring process used,for primer-surfacer and topcoat and is necessary to protect heat sensitive components on completely assembled vehicles. "In-line Repair" means the operation performed and coating used tocorrectdamage or imperfections in the topcoat on parts that are on a completely assembled vehicle. The curing of the coatings applied in these operations is accomplished atessentially the sametemperature as that used for curing the previously applied topcoat. Also referred to as high bake repair or high bake reprocess. In-line repair is considered partofthe topcoatoperation.

"Primer-surfacer operation" means the application area or areas, flashoff area or areas, and oven or ovens that are used to apply and dry or cure primer-SUrfacer between the prime coat and the topcoat operations on components ofautomobile and light-duty truck bodies on a single assembly line.



### 3"Primer-surfacer" means an intermediate protective coating applied over the electrodeposition primer and under the topcoat. Primer-surfacer provides adhesion, protection and appearance properties to the total finish. Primer-surfacer may also be called guide coat or surfacer. Primersurfacer operations may include other coatings (e.g., anti-chip, lower-body anti-chip, chip resistant edge primer, spot primer, blackout, deadener, interior color, basecoat replacement coating, etc) thatare applied in the same spray booth.

### 453/R-08-002, September2008. "Solids turnover ratio (RT )" means the ratio of total volume of coating solids that is added to the EDP system in acalendar month divided by thetotal volume design capacity ofthe EDP system.
