Towing companies have discovered GPS Crash Plastic Wrap/plastic sheeting as a way to add value for their customers, while simplifying their work when they pick up a vehicle that has been in an accident. It used to be that cars that had their windows shattered needed that window to be taped up- to insure the broken glass didn't scatter during towing. Enter duct tape and tarps. You know what is required to tape up a window in this fashion. Not the simpliest way to get the job done.
Today with the advent of GPS Crash Plastic Wrap, the job is quick and easy. The crash wrap is self adhesive- so it sticks to the frame of the vehicle (as long as it is clean and dry). Just pull off the amount you need to cover the window area and let it do its job. It will stay in place until you want to remove it. The best part comes when there has been rain or dust. The inside of the car is protected by the crash wrap. When the owner of the vehicle comes to get their vehicle, they will thank you for protecting the inside of the vehicle. It's traumatic enough to face your vehicle after it has been in an accident. Finding that the interior isn't flooded is a welcome relief.
How do you charge for this service? That is the point. You are offering a service of securing the openings of the vehicle with plastic sheeting. Many of our customers charge by the type of window opening. $25 for each side window, $35-45 for a front or rear window. Charging by the foot makes this service about the amout of crash wrap used on the job. Charge for your time, and the fact that you care enough to do a good job. That people are willing to pay for.
