In step 10 was the construction of the individual links. They were at times tricky,but thank goodness Bronco,included extras. After drying overnight, I applied red enamel primer and for the tracks and under the fenders before installation. Just for the heck of it I shot some black in the interior area to use as a primer undercoat,because I was running short of the red oxide. In step 11, I then installed the left and right fenders,which fitted very tight.
