parkingstripe.com is not the only company to do advertisements on the parking lines. For instance, Tarmac Media (www.tarmacmedia.com) and Aapglobal (aapglobal.com) both do advertising stripes as well. They are very effective and I would be able to answer any of your questions about those advertisements. They are generally insured and maintained. Companies like Tarmac Media and ParkingStripe.com will check them every day for damage and replace any damage. They are only meant for temporary ad campaigns (30 day, 60 day, 90 day, 6 month, or a year), so they aren't painted over.
The biggest issue with these ads is the cost. They are fairly expensive, though highly effective because of the point of sale advertising. Tarmac Media makes them cheaper by printing them in-house, they also stripe parking lots without advertisements, and specialize in multiple other outlets of advertising (both traditional and non traditional).
Although Tarmac Media doesn't have as pretty of a website as PrakingStripe.com, they are less expensive and have offices in Utah and Texas as well as the availability of numerous parking lots around the country. Tarmac Media was formed in 2009 while ParkingStripe.com was formed in 2003. ParkingStripe.com removed themselves somewhat from the installation, maintainence, and sales when Tarmac Media was started. The two companies do not compete directly and have collaborated efforts in the past.
Numerous large companies have seen success with Tarmac Media Stripes and ParkingSripes such as Nationwide Insurance, United Airlines, Starbucks Coffee, and the Colorado Lottery. To view three case studies please visit www.TarmacMedia.com and click on the projects page.
