I have installed two vans for a client using cut vinyl. I used a 3M 7125/7175 series cast vinyl. The installation took place in fall of 2010 and both vehicles have the same problem of the edges coming off. I can still see the adhesive on the vehicle in which has attracted dirt. Can anyone tell me if they have seen this before, and what the cause actually is? I have talked to other installers who have been installing cut vinyl on vehicles for over 30 years, and none have seen this before. Anybody with any experience with this, I would like to know what you found out. I have other vehicles for this client in which were done 2 years before these were installed, and the vinyl still looks fantastic.
