One of the most important keys to a quality XO2 application is a clean surface. After scuffing a surface with a cup brush, you are left with debris and dust. Leaving this behind will block the adhesion powers of 8001 creating weaknesses in the coating bond.
We suggest using Prime Bond paint prep cleaner. Prime Bond Cleaner is a fast evaporating, high quality pre-paint cleaner. This paint prep cleaner dries quickly and will not leave behind any residue.
