Credits: 7
Lecture Hours: 3
Lab Hours: 8
Practicum Hours: 0
Work Experience: 0
Course Type: Voc/Tech
This course covers the application techniques and equipment used in auto collision repair shops for refinishing, and will deal with potential problems with chemicals. Sheet metal and plastic parts repair and replacement in preparation for painting will also be studied in the lab. Shop and personal safety will be emphasized.
