How to put a blackout line on the backglass of a Camaro

  Answer:  If you take the glass out completely, you can easily straight edge cut a piece of blackout tint before replacing it. Lay out the piece, clean it thoroughly, then put the primer on. After letting the primer dry you can tint as normal. If you can’t take it out, then the easiest way to black it out is to paint it, but if the car has old original tint on the other windows, it may difficult to match the backglass to the rest of the car. Old black primer can be removed just by carding over it.
