Good morning, I've been having some issues with my oil slick vinyl. I've ordered from two different companies and no avail. The vinyl is sticking to the backing paper. I've tried the depth of the blade but I am leaving no impression on the backing paper. I've noticed when I Try to separate the vinyl from the backing paper(fresh roll) It doesn't peel off smoothly it stops every 3 cm or so. I am clueless on what to do. Thank you for the help.
