I just finished painting my Bronco II a few days ago. My dad and I did it in our garage. The color needs a flash time of about 10-15 minutes between coats. Once the last coat of color is sprayed, you have to let it set for at least a half hour to an hour before applying the clear coat. I let mine set in the garage over night after I put on the color and sprayed the clear the next morning. Once you start applying the clear, give it about 15 minutes flash time in between coats. After 3 coats of clear, if you want to add more, wait a full 24 hours, wetsand, and then you can apply more coats of clear. Make sure you keep the temperature warm enough (about 75 degrees or so) and make sure everything is as clean as possible before you start spraying.
