I do detailed fineline work, and have found so many stencil gels don’t hold the crispness I want, or take forever to dry and be ready for tattooing so they wont disappear after a few wipes. However the Metrix Primer has been amazing, no “gotta do it this super specific way” messing around, or waiting forever for it to do its job. Holds the stencil amazing & keeps it clear. Best I’ve ever used. Also has a nice subtle smell, & great dispenser with the airless pump system, which are both great additional features. Can actually use every drop & doesn’t require much product to work perfectly, works out very worth its money. Highly recommend.
