Tried Mob m80 on a board fairly recently, both purchased from a local. Fresh batch of grip, too. Gripped, brought it home and it sat there for a day. Went to set it up, adhesive properties became non existent and I pulled the entire sheet off with barely any struggle. Top ply wasn’t even sticky after pulling it off.
Got regular Mob, adhesive worked but left a crease/wrinkle on my nose that never laid down. Swore off Mob. Grabbed regular Jessup for my next board, always reliable. Nope, my edges are melting off from the slightest scrapes. And yeah, I know how to score, slice, and sand the edges properly. Might just have to revisit black magic now?
