When resin is produced and packaged it is done in several hundreds of gallons at a time. If a bad batch were to happen it wouldn't affect just one or two orders it would affect hundreds. If you have been using resin for a while and all of a sudden start having issues it usually drills down to a process issue or an environmental change that is causing it. Nevertheless, we are more than happy to troubleshoot with you if this ever occurs, so please reach out to our support team if you have questions! support@counterculturediy.com.
