I am "attempting" to repaint a 1987 Jeep Comanche. I have sanded the entire vehicle with 220 grit because the old clear coat was chipping off as well some of the paint in areas that someone had previously done some body work. I did not go to bare metal because most of the paint was in decent shape. I have shot about 2/3 of the vehicle with a 1K Acrylic primer surfacer. After reading many articles I am thinking I should have used a 2K primer. Can I , or would it make any sense , to sand the 1K with 320 grit and respray with 2K ? I am going to a SS urethane topcoat ? I'm afraid to move forward with this project cause I don't want to mess it up. Thank you in advance for your advice.
