Im assuming if my math is correct, u used about 12 cans to Paint your blazer? I got a second gen and im looking into doing a paint job next summer and trying to judge how many cans I need...

 

depends how many coats you do and how thick, etc

the suburban i posted took 8 cans total, just did one thick coat. it was like one can per 1 1/2 have body panel and i didnt pain the roof. so one spray can would do a entire fender and half the door basically
