ARMOR needs a short-pile fabric roller

• Use a fabric roller with the shortest pile you can find. Foam and flock rollers are out - ARMOR dissolves them, they swell and leave tiny craters.
• Swap the roller about every 30 minutes: paint dries on it, the pile clumps and starts shedding. Get a few for a whole car.
• Roll lightly, without pressing. You want a fine, even texture - ARMOR is not meant to go on smooth.
