I just received an e-mail from 3M regarding the process for handling defective 3M ATG adhesive dispensers. They have updated their process and wanted me to disseminate this information:
Please contact 3M by calling 888.936.3636 Monday through Friday 8am-5pm Central Time. Please feel free to leave a voicemail during evenings and weekends.
I have postings on my blog regarding my experiences, which you can view here:
