Last week I discovered a way to just about completly hide that sometimes tell-tale front edge showing on certain skin units.
I liberally applied to the front edge, their G2BG Ultra Glued product, in a a Black & Silver Tube. The front edge kinda buried itself in the product. Like a lace wearer burying the lace in the glue.
There was no front edge showing when checked in brilliant sunlight with a magnifying 5x mirror !
Please post here , your findings if you try this .
