A lot of people don’t know, but Jessup is actually a grit/adhesive company that has been around for decades and has stuff for all types of industries and applications. There was a dude that worked for them that decided to market the specific grit used for skateboarding as what we all know it to be. They’re USA made and manufactured. It’s always been consistent, affordable, and practical.
Mob regular and M80 is imported, and of all the times I’ve used it, it feels like it’s not specifically for skateboards. Yeah, you could use Jessup for anything you need it for, but it just FEELS natural for a board. The way it lays and cuts is like butter. Mob doesn’t form well, and it cuts pretty rough, fresh or dull blade.
The only downside to Jessup is during really hot summer days the edges kinda melt even if I sanded well, but it doesn’t really affect the performance it just looks sketchy. Mob was more resilient in that regard.
