Use Film Tech for Durable Flat Surface Sanding

that's what's yellow Eccostorm cuts and sands a lot faster if you're trying to sand really, really quick. It's a paper abrasive. So the yellow Eccostorm's paper, the blue film tech is actually plastic which will last a lot longer. It won't rip or tear. So I usually have, I would say predominantly film tech, but Eccostorm, you'll sands your closet packs like a lot faster. So I'm typically using a 320. So I have two film techs on 320.
