After Glow is a specifically formulated drying aid, but can be used as a standalone sealant when added to dry paint to add protection. The way you use this one is to get two of our Big Softie cloths. Using clean, fresh water, completely drench one cloth, and then wring it out till it's just damp. Fold the damp cloth into quarters, to the low pile side, and then spray 3-4 sprays of After Glow into the cloth. Work on one panel at a time, work in side-to-side motions; up and down/side to side. Leave the product to flash off for around 1 minute, then buff off any remaining residue with your second Big Softie cloth, again folded into quarters to the low pile side. Continue this technique for the entire vehicle.
