unfortunately there'a ton of bad installers listed on that map. You're just copying the UASG site
We are using the UASG companies, the PDAA Master Certified and the 3M Preferred to start populating the map (as well as applicants IDed as independents). These are documented, tested and Certified pros who are involved in a systematized program with a nationally recognized and documented level of accountability. Given the alternative of a free-for-all approach I felt this was the best way to offer a valuable resource.
Regarding your opinion of "a ton of bad installers" I have been kicking around the idea of adding some sort of rating system. As I have thought it out, it occurs to me that it would be very important to come up with a fair and balanced way to review competence, professionalism, etc. We would also need to weight it considering the source of the review. While a particular end user might think a wrap is awesome, a pro might see all sorts of issues. Definitely a considerable challenge for the future.
Seano... We have just started to add the 3M Preferred guys.
