The Happ stuff is thicker/heavier/tougher. I couldn't get it to fold over an edge without some degree of bubbling so you'd have to cut it flush. That being said it's great for front panels, CP tops/boxes.
It is a very fine texture, no problems with sideart.
It's way too expensive normally. Ponyboy might be able to get you a decent price if it's not on sale at Happ.
