See Justin and Rainer wrap a back bumper in realtime using the TWI Zero Stretch and TWI Wrap Matrix. This is a great watch as you get to see the full process start to finish with no editing. Pluse, they wrap it in small squares and entirely in one piece! Be sure to pay attention to how they use the built in stretch from the film to wrap the vehicle for them. This works great for cast and calendar wrap films. heat gun, squeegee, buffer, heat gun, knife, blade, safe box, race ramps index: back bumper - wrap matrix tags: back bumper, realtime, zero stretch, squares, rainer, justin, license plate, one piece
